TECHNICAL FIELD

The present disclosure relates to a pixel arrangement structure anddriving method thereof, display substrate and display device.

BACKGROUND

Nowadays, the continuous developments of the display technique has ledto higher requirements to the display resolution and the higher displayresolution in turn would increase the techniques complexity and cost forpreparing and making displays. When the display resolution is at asimilar level of the naked-eye resolution, the conventional mode ofusing three sub-pixels namely red (R), green (G) and blue (B) fordefining one pixel briefly may be changed, based on the differences ofnaked eyes in distinguishing different colored pixels. That is, bysharing some sub-pixels which color have less sensitive resolutions atcertain location in different pixels, and using relatively lesssub-pixels to simulate the same pixel resolution performance, complexityand cost of the Fine Metal Mask (FMM) techniques is reduced.

DETAILED DESCRIPTION

Solutions in the embodiments of the present disclosure will be describedclearly and completely below in conjunction with the accompanyingdrawings of the embodiments of the present disclosure. It is obviousthat the described embodiments are only part of the embodiments of thepresent disclosure, but not all the embodiments. Based on theembodiments of the present disclosure, other embodiments obtained bythose ordinary skilled in the art without creative labors would belongto the protection scope of the present disclosure.

With reference to FIG. 1, in some related arts, in the row direction,red, green, blue, and green sub-pixels are arranged in cycles, whereinin each pixel 10, there is an independent green sub-pixel 103, a redsub-pixel 101 and a blue sub-pixel 102 located on both sides and sharedby the adjacent pixels 10, thus the sub-pixel density in the directionof rows is two times of the pixel density, and the sub-pixel density inthe direction of columns is the same as the pixel density.

With reference to FIG. 1, one red sub-pixel 101 and one green sub-pixel103 form a pixel 10, and one blue sub-pixel 102 and one green sub-pixel103 form a pixel 10. The pixel here only includes two sub-pixels withdifferent colors. It is necessary for the pixel to borrow or share asub-pixel of other pixels to realize color display. Therefore, the pixel10 here may be called virtual pixel.

Accordingly, although the same resolution ratio may be achieved with afew sub-pixels, in the direction of rows the sub-pixel density is stillequal two times of the pixel density, which results in high requirementsto the FMM technique level.

An embodiment according to the present disclosure provides a pixelarrangement structure, comprising a plurality of repeating units, eachrepeating unit comprising one first sub-pixel, one second sub-pixel andtwo third sub-pixels.

The four sub-pixels of each repeating unit constitute two pixels, thefirst sub-pixel and the second sub-pixel being shared by the two pixels.In a first direction of the pixel array, the sub-pixel density is equalto 1.5 times of the pixel density, in a second direction of the pixelarray, the sub-pixel density is equal to 1.5 times of the pixel density.The first direction and the second direction are different directions.

It is to be noted that, in the first aspect, the pixel arrangementstructure according to the embodiments of the present disclosure can beapplied to any display device composed of three sub-pixels such as red,green and blue sub-pixels. Examples of the display device may be LiquidCrystal Display (LCD) and Organic Light-Emitting Diode (OLED) etc.

In the second aspect, since the first sub-pixel and the second sub-pixelof each pixel are shared by two pixels, the pixels according to theembodiments of the present disclosure cannot be considered as realpixels in a strict definition, where a pixel is defined by a completeone first sub-pixel, one second sub-pixel and one third sub-pixel.Therefore, the pixels of the present disclosure may be called virtualpixels.

Since the first sub-pixel and the second sub-pixel are shared by twopixels, the boundary of each virtual pixel is blurry. Thus, the shape ofeach pixel is not defined by the embodiments of the present disclosure.

In the third aspect, it is known to a person skilled in the art that,based on the pixel arrangement structure, the pixels and the firstsub-pixel, the second sub-pixel and the third sub-pixels in each pixelmay be distributed evenly.

In the fourth aspect, the first and second directions as illustrated inthe accompanying drawings are only illustrations in a general view, thatis, in order to satisfy that sub-pixel density is 1.5 times of pixeldensity and pixels and each sub-pixel in pixels are evenly distributedin overall, the first direction in a closer view might not be acompletely straight line but wavy lines, the same applies to the seconddirection.

The first direction and the second direction may be for example twodirections being perpendicular to each other in the same plane, such asthe plane where the pixels are arranged.

Embodiments of the present disclosure provide a pixel arrangementstructure, since the four sub-pixels in each repeating unit may form twopixels, wherein the first sub-pixel and the second sub-pixel are sharedby two pixels, in the first direction of the pixel array, the sub-pixeldensity is 1.5 times of the pixel density, in the second direction ofthe pixel array, the sub-pixel density is 1.5 times of the pixeldensity. Compared to the technologies in the art where in one direction,the sub-pixel density is two times of the pixel density and in anotherdirection, the sub-pixel density is equal to the pixel density, theembodiments of the present disclosure reduces the sub-pixel densitywhile balancing the quantity of the sub-pixels in two directions, thusmay avoid having too many sub-pixels in one particular direction. Thuswhen the pixel arrangement structure is applied to a display panel, theFMM techniques complexity for making the pixels of the display panel maybe reduced in overall.

In an example, the first sub-pixel is red sub-pixel, the secondsub-pixel is blue sub-pixel, and the third sub-pixel is green sub-pixel.

In other words, the pixel arrangement structure comprises a plurality ofrepeating units, wherein each repeating unit comprises one firstsub-pixel, one blue sub-pixel and two green sub-pixels; the foursub-pixels of each repeating unit constitute two pixels, the redsub-pixel and the blue sub-pixel being shared by the two pixels; in afirst direction of the pixel array, the sub-pixel density is equal to1.5 times of the pixel density, in a second direction of the pixelarray, the sub-pixel density is equal to 1.5 times of the pixel density;wherein, the first direction and the second direction are differentdirections.

It is to be noted that, in the first aspect, since the red sub-pixel andthe blue sub-pixel of each pixel are shared by two pixels, the pixelsaccording to the embodiments of the present disclosure cannot beconsidered as real pixels in a strict definition, where a pixel isdefined by a complete one red sub-pixel, one green sub-pixel and oneblue sub-pixel. Therefore, the pixels of the present disclosure may becalled virtual pixels.

Since the red sub-pixel and the blue sub-pixel are shared by two pixels,the boundary of each virtual pixel is blurry. Thus, the shape of eachpixel is not defined by the embodiments of the present disclosure.

In the second aspect, it is known to a person skilled in the art that,in the case of high resolution, the green sub-pixels play a criticalrole in deciding the perceived luminance central position of each pixel.Thus, based on the embodiments of the present disclosure, the greensub-pixels in each pixel may be in overall distributed evenly.

Since the embodiments of the present disclosure requires that whether inthe first direction or in the second direction, the sub-pixel density is1.5 times of the pixel density, causing difficulties for the greensub-pixels to be distributed with equal space in all the locations.Accordingly, the embodiments of the present disclosure may achieve theeven distribution of the green sub-pixels in overall in a range of morethan three pixel-spaces by slightly adjusting the relative position ofthe green sub-pixels in different rows and columns.

Based on this, the red sub-pixels and the blue sub-pixels shared by twoadjacent pixels may be evenly distributed as much as possible togetherwith the green sub-pixels.

In an example illustrated in FIG. 2(a) and FIG. 2(b), in the firstdirection, the green sub-pixels 103 are disposed in pairs and withineach pair, two green sub-pixels are adjacent to each other; a redsub-pixel 101 and a blue sub-pixel 102 is disposed between any twoadjacent pairs of green sub-pixels 103. For example, the greensub-pixels disposed in pairs, in each of which two sub-pixels beingadjacent to each other, forms a plurality of green sub-pixel pairsarranged in the first direction. For example, the two green sub-pixelsof each green sub-pixel pair are arranged in the first direction.

With reference to FIG. 2(a) and FIG. 2(b), two adjacent green sub-pixelsforming a green sub-pixel pair and one red sub-pixels and one bluesub-pixel arranged at the green sub-pixel pair form a repeating unit. Aplurality of repeating units are arranged along the first direction toform a plurality of repeating unit groups. Each dash line in ahorizontal direction refers to a center line of a repeating unit groupor a repeating unit row formed by repeating units arranged in the firstdirection. In this embodiment, the red sub-pixel and the blue sub-pixelin each repeating unit are arranged in the second direction, the greensub-pixel pairs are arranged in the first direction. The arrangement ofthe repeating unit group is not limited in the embodiment. For example,an arrangement way is to arrange the red sub-pixel, the blue sub-pixeland the green sub-pixel pairs sequentially in the first direction, andanother arrangement way is to arrange the red sub-pixel and the bluesub-pixel between the green sub-pixel pairs.

In other words, all the green sub-pixels 103 in the first direction arein pairs, within each pair the green sub-pixels are disposed adjacent toeach other.

Based on this, in a preferred embodiment, a red sub-pixel 101 and a bluesub-pixel 102 between any two adjacent pairs of green sub-pixels 103 areopposed to each other in the second direction.

Here, as in the first direction, the red sub-pixel 101 and the bluesub-pixel 102 are both disposed between two adjacent pairs of greensub-pixels 103, the requirement that the sub-pixel density is 1.5 timesof the pixel density may thus be satisfied. The proportion of thenumbers of the red sub-pixels 101, the green sub-pixels 103 and the bluesub-pixels 102 may be 1:2:1.

For example, four sub-pixels are included in a location illustrated bythe two dash circles in FIG. 2(a). The four sub-pixels are located inthree sub-pixel rows and three sub-pixel columns, respectively. Forexample, the red sub-pixel is in the first row, the two green sub-pixelsare the second row, and the blue sub-pixel is in the third row;accordingly, the green sub-pixel is in the first column, the redsub-pixel and the blue sub-pixel are in the second column, and the greensub-pixel is in the third column. The four sub-pixels may constitute twovirtual pixels, i.e. a virtual pixel constituted by one red sub-pixeland one green sub-pixel and a virtual pixel constituted by one bluesub-pixel and one green sub-pixel. That is, sub-pixels in threesub-pixel rows and three sub-pixel columns constitute pixels in twopixel rows and two pixel columns; therefore, the sub-pixel density is1.5 times of the pixel density both in the row direction and in columndirection. For example, repeating units are arranged to form repeatingunit rows or repeating unit columns, the rows and the columns are formedby taking the repeating unit as a whole. Each repeating unit itselfincludes a plurality of sub-pixel rows and a plurality of sub-pixelcolumns. For example, each repeating unit includes three rows ofsub-pixels or three columns of sub-pixels. For example, as illustratedin FIG. 2(a), in each repeating unit, the two green sub-pixels are in arow, one red sub-pixel is in a row, and one blue sub-pixel is in a row.

In some embodiments of the present disclosure, as in the first directionall the green sub-pixels 103 are disposed in pairs in each of which twogreen sub-pixels are adjacent to each other, during preparation of theOLED using the FMM vapor-deposit technique, it is possible to connectthe color layer of the two green sub-pixels 103 of each pair, and toform a green luminescence layer of the two green sub-pixels 103 of eachpair via one FMM vapor-deposit hole, thus at some extent reducing thetechniques complexity for preparing and making the color layer of thegreen sub-pixels 103.

Further, in the embodiments of the present disclosure, the adjacentgreen sub-pixels 103 may be disposed side by side along the firstdirection, and slight adjustments of the position of the greensub-pixels 103 may permit even distribution of the virtual pixel array.Also, by keeping certain distance between two most adjacent greensub-pixels, it may reduce the complexity of the techniques whileguaranteeing the horizontal and vertical lines of the centers of thebright spots to be smooth and continuous (as illustrated in dash linesin FIG. 2(a) and FIG. 2(b)).

For example, as illustrated in FIG. 2(a) and FIG. 2(b), the shape of thered sub-pixels 101 and the blue sub-pixels 102 are both trapezoid, abase of the red sub-pixels 101 and a base of the blue sub-pixels 102 aredisposed to be opposite to each other.

The shape of each green sub-pixel 103 is pentagon, the pentagoncomprises a pair of parallel opposite sides and a perpendicular side,the perpendicular side being perpendicular to the pair of parallelopposite sides; wherein the perpendicular sides of each pair of thegreen sub-pixels 103 are disposed adjacent to each other; the bases ofthe red sub-pixels 101 and of the blue sub-pixels are parallel to thepair of parallel opposite sides of the green sub-pixel 103.

It is to be noted that, the shape of the red sub-pixels 101 and the bluesub-pixels 102 ideally may be trapezoid, but in the actual FMM process,as the metallic etching may cause draft angles, so when using FMMvapor-deposit techniques for making read sub-pixels 101 and bluesub-pixels 102, the form of such formed red sub-pixels 101 and bluesub-pixels 102 may not be a standard trapezoid but in the shape asillustrated in FIG. 2(c). In an example illustrated in FIG. 2(c), theshape is a trapezoid with a corner being cut off.

In addition, although a shape of each sub-pixel in the drawings includesan angle formed by two standard line segments, in some embodiments, eachsub-pixel may have a shape with rounded corners. That is to say, basedon the above shapes of various pattern illustrated in figures, cornersof each sub-pixel is rounded. For example, in the case where alight-emitting layer is vapor-deposited by a fine metal mask (FMM), apart of the light-emitting layer located at the corner may naturallyform a shape with rounded corner.

In the embodiments of the present disclosure, as two green sub-pixels103 are disposed adjacent to each other, during preparation of the OLEDusing the FMM vapor-deposit technique, it is possible to connect thecolor layer of the two green sub-pixels 103 of each pair, and to form agreen luminescence layer of the two green sub-pixels 103 of each pairvia one FMM vapor-deposit hole, thus reducing the techniques complexityof the FMM techniques. As illustrated in FIG. 2(a) and FIG. 2(b), thegreen sub-pixels 103 as the luminance center of the virtual pixels, inthe first direction, all of the green sub-pixels 103 are on the verticaldash lines, in the second direction, all of the green sub-pixels 103 areon either side of the vertical dash lines, and the green sub-pixels 103are evenly distributed in the pixel array, thus guaranteeing that thehorizontal and vertical lines of the center of the luminance to besmooth and continuous (as illustrated in dash lines in FIG. 2(a) andFIG. 2(b)).

Further, as illustrated in FIG. 2(a), the shorter base of the redsub-pixel 101 and the shorter base of the blue sub-pixel 102 aredisposed to be adjacent to each other. In other words, the shorter baseof the red sub-pixel 101 and the shorter base of the blue sub-pixel 102are disposed to be opposed to each other.

In the embodiments of the present disclosure, a red sub-pixel 101 and ablue sub-pixel 102 are disposed between any two adjacent pairs of greensub-pixels 103, and since the shape of the red sub-pixel 101 and of theblue sub-pixel 102 is trapezoid, the shorter base of the red sub-pixel101 and the shorter base of the blue sub-pixel 102 are disposed adjacentto each other, such that the distance between the green sub-pixels 103and the red sub-pixels 101 as well as the blue sub-pixels 102 isrelatively far, which is advantageous for the FMM design, and forreducing the FMM techniques complexity.

For example, in the second direction, the green sub-pixels 103 aredisposed in pairs in each of which two sub-pixels are adjacentlydisposed, and one red sub-pixel 101 and one blue sub-pixel 102 aredisposed between any two adjacent pairs of the green sub-pixels 103.

In other words, in the second direction all the green sub-pixels 103 aredisposed in pairs, and in each pair two green sub-pixels 103 aredisposed adjacent to each other.

Based on this, in an example, one red sub-pixel 101 and one bluesub-pixel 102 between any two adjacent pairs of green sub-pixels 103 aredisposed to be opposed to each other in the first direction.

Here since in the second direction, the red sub-pixels 101 and the bluesub-pixels 102 are all disposed between two adjacent pairs of greensub-pixels 103, thus the requirement that the sub-pixel density is 1.5times of the pixel density may be satisfied. The proportion of thenumbers of the red sub-pixels 101, the green sub-pixels 103 and the bluesub-pixels 102 may be 1:2:1.

It is to be noted that in the second direction, the green sub-pixels 103are disposed in pairs and within each pair two green sub-pixels 103 aredisposed adjacent to each other; one red sub-pixel 101 and one bluesub-pixel may be disposed between any two adjacent pairs of greensub-pixels 103, which allows that in the first direction and in thesecond direction, the sub-pixel density is 1.5 times of pixel densityand the virtual pixel array is evenly distributed. For example, thegreen sub-pixels which are in pairs and within each pair the two greensub-pixels being adjacent to each other forms a plurality of greensub-pixel pairs arranged in the second direction. For example, the twogreen sub-pixels in each green sub-pixel pair are arranged in the seconddirection.

In the embodiments of the present disclose, in the second direction allthe green sub-pixels 103 are disposed in pairs and within each pair twogreen sub-pixels being adjacent to each other, during preparation of theOLED using the FMM vapor-deposit technique, it is possible to connectthe color layer of the two green sub-pixels 103 of each pair, and toform a green luminescence layer of the two green sub-pixels 103 of eachpair via one FMM vapor-deposit hole, thus at some extent reducing thetechniques complexity for preparing and making the color layer of thegreen sub-pixels 103.

Further, in the embodiments of the present disclosure, the adjacentgreen sub-pixels 103 may be disposed side by side in the seconddirection, and slight adjustments of the position of the greensub-pixels 103 may permit even distribution of the virtual pixel array.Also, by keeping certain distance between two most adjacent greensub-pixels 103, it may reduce the complexity of the techniques whileguaranteeing the horizontal and vertical lines of the centers of thebright spots to be smooth and continuous (as illustrated in dash linesin FIG. 3(a) and FIG. 3(b)).

In some embodiments, as illustrated in FIG. 3(a) and FIG. 3(b), theshapes of the red sub-pixels 10 and the blue sub-pixels 102 are bothhexagon, the three pairs of opposite sides of the hexagon having eachpair of sides parallel to each other.

In addition, although a shape of each sub-pixel in the drawings includesan angle formed by two standard line segments, in some embodiments, eachsub-pixel may have a shape with rounded corners. That is to say, basedon the above shapes of various pattern illustrated in figures, cornersof each sub-pixel is rounded. For example, in the case where alight-emitting layer is vapor-deposited by a FMM, a part of thelight-emitting layer located at the corner may naturally form a shapewith rounded corner.

The shape of each green sub-pixel is pentagon, the pentagon comprises apair of parallel opposite sides and a perpendicular side, theperpendicular side being perpendicular to the pair of parallel oppositesides; wherein the perpendicular sides of each pair of the greensub-pixels 103 are disposed adjacent to each other.

The pair of parallel opposite sides of the red sub-pixels 101 withlonger length and the pair of parallel opposite sides of the bluesub-pixels 102 with longer length, are parallel to a pair of parallelopposite sides of the green sub-pixels 103.

Here it is to be noted that, positions of the red sub-pixels 101, theblue sub-pixels 102 and the green sub-pixels 103 in each repeating unitmay be adjusted in an arbitrary manner as long as in the first directionand in the second direction of the pixel array, the sub-pixel density is1.5 times of the pixel density, for example, as those illustrated inFIG. 3(a) or in FIG. 3(b).

It is noted that although some shapes of the sub-pixels in accordancewith the embodiments of the present disclosure are described withreference to FIG. 2(a)-FIG. 3(b), the embodiments according to thepresent disclosure shall not be limited to those drawings and thesub-pixels according to the present disclosure may be in the any othershapes that may be suitable.

In the embodiments of the present disclosure, given that the pair ofparallel opposite sides of the red sub-pixels 101 with longer length andthe pair of parallel opposite sides of the blue sub-pixels 102 withlonger length, are parallel to a pair of parallel opposite sides of thegreen sub-pixels 103, in one aspect, each FMM opening may be designed tobe quasi-hexagon, thus favoring the FMM design; in another aspect, whenFMM vapor-deposit techniques is adopted to vapor-deposit the sub-pixels,the net tensile force will be mainly applied on the longer side, thusavoiding damages to the FMM and favoring the success rate of nettension.

For example, as illustrated in FIG. 3(a) and FIG. 3(b), the redsub-pixel and the blue sub-pixel in each repeating unit are arranged inthe first direction, and a pair of green sub-pixels are arranged in thesecond direction. In addition, the red sub-pixel, the blue sub-pixel andthe green sub-pixel pair may be arranged in the first direction insequence, or the green sub-pixel pair is arranged between one redsub-pixel and one blue sub-pixel.

As illustrated in FIG. 3(a) and FIG. 3(b), a plurality of repeatingunits arranged in the first direction form a plurality of repeating unitgroups (repeating unit rows). For example, a dash line in the firstdirection refers to a central line of each of the plurality of repeatingunit groups. The plurality of repeating unit groups are arranged in thesecond direction to form the pixel arrangement structure.

For example, in the above pixel arrangement structure, adjacentrepeating unit groups are shifted in the first direction. That is,adjacent repeating unit groups have an offset in the first direction;therefore, sub-pixels of the same color in adjacent repeating unitgroups are not aligned in the second direction. In some examples, anoffset of adjacent repeating unit groups in the first direction is ahalf of a size of the repeating unit in the first direction. Forexample, the size of the repeating unit in the first direction is apitch of the repeating units in the first direction.

As illustrated in FIG. 3(a) and FIG. 3(b), the repeating unit groups inodd-numbered rows have the same pixel arrangement manner, and therepeating unit groups in even-numbered rows have the same pixelarrangement manner. For example, except the edge portion of the pixelarrangement structure, a line passing through centers of the two greensub-pixels in each repeating unit is located between centers of adjacentred sub-pixel and blue sub-pixel in adjacent repeating unit groups.Moreover, edges of the two green sub-pixels are located at an inner sideof the outermost edges of the above-mentioned adjacent red sub-pixel andblue sub-pixel, and the outermost edges are the edges away from eachother along the first direction of the two sub-pixels. For example, ifthe two sub-pixels are arranged along the first direction from a leftside to a right side, the outermost edges of the two sub-pixels are theleft edge of the sub-pixel at the left side and the right edge of thesub-pixels at the right side. That is, in the first direction, anextending range of one green sub-pixel pairs in the first direction isnot beyond an extending range of the above-mentioned adjacent redsub-pixel and blue sub-pixel in the first direction.

For example, for the above-mentioned pixel arrangement structure, aratio of the sub-pixels of red, blue and green is 1:1:2. One redsub-pixel and one green sub-pixel constitute a pixel, and one bluesub-pixel and one green sub-pixel constitute a pixel. The specificcombinations of sub-pixels in each pixel are not limited in theembodiments of the present disclosure. For example, one red sub-pixeland one green sub-pixel in a repeating unit constitute a pixel, and oneblue sub-pixel and one green sub-pixel in the repeating unit constitutea pixel. Alternatively, for the green sub-pixel pairs in the samerepeating unit, one of the green sub-pixels and one red sub-pixel in therepeating unit form a pixel, and the other of the green sub-pixels andone blue sub-pixel in an adjacent repeating unit form a pixel.

For example, as illustrated in FIG. 3(a) and FIG. 3(b), green sub-pixelsare arranged in the second direction, a size of the red sub-pixel in thesecond direction is greater than that of the red sub-pixel in the firstdirection, similarly, a size of the blue sub-pixel in the seconddirection is greater than that of the blue sub-pixel in the firstdirection.

The embodiments of the present disclosure provides a display panel,pixels of the display panel are arranged according to theabove-described pixel arrangement structure.

The embodiment of the present disclosure also provides a display device,which comprises the above-described display panel.

The display device in accordance with the embodiments of the presentdisclosure can be applied to any display device including threesub-pixels such as red, green and blue sub-pixels, for example, liquidcrystal display (LCD) and organic light-emitting diode (OLED), etc.

In the study, the inventor(s) of the present application notices that:in order to manufacture a high-resolution display device, it isnecessary to reduce a pixel size and a pixel pitch; however, reductionin the pixel size and the pixel pitch is also increasingly demanding forprecision of manufacturing process, which may result in increaseddifficulties and costs in a manufacturing process of the display device.For example, upon a high-resolution active matrix organic light emittingdiode (AMOLED) display device being manufactured, due to a limitation inprocess precision of a fine metal mask (FMM) technology, it is difficultand expensive to manufacture the active matrix organic light emittingdiode (AMOLED) display device having high resolution (for example,Pixels Per Inch (PPI) greater than 300).

At least one embodiment of the present disclosure provides a pixelarrangement structure. FIG. 4 is a schematic diagram of a pixelarrangement structure provided by an embodiment of the presentdisclosure. The pixel arrangement structure comprises a plurality offirst color sub-pixel blocks 111, a plurality of second color sub-pixelblocks 112 and a plurality of third color sub-pixel blocks 113distributed in a plurality of minimum repeating regions 100. FIG. 4shows one minimum repeating region 100; as illustrated by FIG. 4, eachof the plurality of minimum repeating regions 100 includes a firstvirtual rectangle 110; and the first virtual rectangle 110 includes onefirst color sub-pixel block 111, one second color sub-pixel block 112and one third color sub-pixel block 113. The first virtual rectangle 110includes a first edge 1101 extending in a first direction and a secondedge 1102 extending in a second direction; the second color sub-pixelblock 112 and the third color sub-pixel block 113 are distributed on twosides of a perpendicular bisector of the first edge 1101; a distancebetween the second color sub-pixel block 112 and the first edge 1101 anda distance between the third color sub-pixel block 113 and the firstedge 1101 are both smaller than a distance between the first colorsub-pixel block 111 and the first edge 1101; and a center of the firstcolor sub-pixel block 111 is located on the perpendicular bisector ofthe first edge 1101 and a distance between the center of the first colorsub-pixel block 111 and the first edge 1101 is approximately ½ to ¾ of alength of the second edge 1102. For example, as illustrated by FIG. 4,the length of the second edge 1102 is L, and the distance between thecenter of the first color sub-pixel block 111 and the first edge 1101 is(½ to ¾)L. It should be noted that, the above-described first virtualrectangle is intended to better describe a position of the first colorsub-pixel block, and is not an actual structure. In addition, a range ofa virtual rectangle of the above-described first virtual rectangle maybe larger than a light-emitting region of the first color sub-pixelblock, the second color sub-pixel block and the third color sub-pixelblock in the first virtual rectangle. The above-described “center”refers to a geometric center of a shape of a sub-pixel block (forexample, the first color sub-pixel block, the second color sub-pixelblock or the third color sub-pixel block); and the above-described “adistance between the second color sub-pixel block and the first edge anda distance between the third color sub-pixel block and the first edge”refer to a distance between the center of the second color sub-pixelblock and the first edge and a distance between the center of the thirdcolor sub-pixel block and the first edge.

In the pixel arrangement structure provided by this embodiment, becausethe second color sub-pixel block and the third color sub-pixel block aredistributed on two sides of the perpendicular bisector of the firstedge, and the center of the first color sub-pixel block is located onthe perpendicular bisector of the first edge and the distance betweenthe center of the first color sub-pixel block and the first edge is ½ to¾ of the length of the second edge, a distance between centers ofadjacent two first color sub-pixel blocks is larger than ½ of the lengthof the second edge, which, thus, can avoid a case where the adjacent twofirst color sub-pixel blocks are difficult to distinguish and arevisually combined into one by human eyes due to a closer distancebetween the adjacent first color sub-pixel blocks, so that granularsensation generated thereby can be avoided. Thus, the pixel arrangementstructure can improve uniformity of distribution of first colorsub-pixel blocks, so as to improve visual resolution and further improvedisplay quality.

It should be noted that, upon designing a pixel arrangement structure,the sub-pixel is generally designed in a regular shape, such as ahexagon, a pentagon, a trapezoid or other shapes. The center of thesub-pixel may be the geometric center of the above regular shape upondesigning. However, in an actual manufacturing process, the shape of theformed sub-pixels generally deviates from the regular shape of the abovedesign. For example, corners of the abovementioned regular shape may berounded; therefore, the shape of the sub-pixel can be a figure withrounded angle. Furthermore, the shape of the actually fabricatedsub-pixel can also have other variations from the shape of the design.For example, the shape of a sub-pixel designed as a hexagon may becomeapproximately elliptical in actual fabrication. Therefore, the center ofthe sub-pixel may also not be the strict geometric center of theirregular shape of the formed sub-pixel. In embodiments of the presentdisclosure, the center of the sub-pixel may have a certain offset fromthe geometric center of the shape of the sub-pixel. The center of asub-pixel refers to any point in a region surrounded by specific pointson radiation segments each of which is from a geometric center of thesub-pixel to a point on the edge of the sub-pixel, each of the specificpoints is located on a corresponding radiation segment at location ⅓ oflength of the radiant section from the geometric center. The definitionof the center of the sub-pixel is applicable to the center of thesub-pixel having the regular shape, and is also applicable to the centerof the sub-pixel having the irregular shape.

For example, in some examples, the above-described minimum repeatingregion can be translated and arranged repeatedly to form a completepixel arrangement structure. It should be noted that any sub-unit thatcan be translated and arranged repeatedly is not included in the minimumrepeating region.

For example, in some examples, the center of the first color sub-pixelblock 111 is located on the perpendicular bisector of the first edge1101 and has the distance between the center of the first colorsub-pixel block 111 and the first edge 1101 is ½ to ¾ of the length ofthe second edge 1102.

It should be noted that, upon the pixel arrangement structure beingdesigned, the sub-pixel block (for example, the first color sub-pixelblock, the second color sub-pixel block or the third color sub-pixelblock) is usually designed to have a regular shape of, for example, ahexagon, a pentagon, a trapezoid, and the like. In design, the center ofthe sub-pixel block may be a geometric center of the above-describedregular shape. However, in an actual manufacturing process, the shape ofthe formed sub-pixel block usually has certain deviation from theregular shape as designed above. For example, respective corners of theabove-described regular shape may become rounded, so the shape of thesub-pixel block (for example, the first color sub-pixel block, thesecond color sub-pixel block or the third color sub-pixel block) may bea rounded shape. In addition, the shape of the actually manufacturedsub-pixel block may further have other variations from the designedshape. For example, the shape of the sub-pixel block designed as ahexagon may become an approximate ellipse in actual fabrication.Therefore, the center of the sub-pixel block may not be the strictgeometric center of the irregular shape of the sub-pixel blockmanufactured. In the embodiment of the present disclosure, the center ofthe sub-pixel block may have a certain offset from the geometric centerof the shape of the sub-pixel block. The center of the sub-pixel blockrefers to any point within a region enclosed by specific points onradiation line segments starting from the geometric center of thesub-pixel block to respective points of an edge of the sub-pixel block,and the specific point on the radiation line segment is located at adistance of ⅓ the length of the radiation line segment from thegeometric center. A definition of the center of the sub-pixel block isapplicable to the center of the shape of the regular-shaped sub-pixelblock, and is also applicable to the center of the irregular-shapedsub-pixel block.

In addition, as described above, due to various fabrication errors, theshape of the actually manufactured sub-pixel block may deviate from theshape of the designed sub-pixel block. Therefore, in the presentdisclosure, a certain error is allowed in a position of the center ofthe sub-pixel block as well as a relationship between the center of thesub-pixel block and a position of any other object. For example, withrespect to a line connecting centers of sub-pixel blocks or a linepassing through the center of the sub-pixel block, if the line satisfiesother corresponding definitions (for example, an extension direction),the line only has to pass through the region enclosed by the specificpoints of the radiation line segments as described above. For anotherexample, if the center of the sub-pixel block is located on a certainline, it refers to that the line only has to pass through the regionenclosed by the specific points of the radiation line segments asdescribed above.

For example, in some examples, the first color sub-pixel block 111, thesecond color sub-pixel block 112 and the third color sub-pixel block 113may separately serve as one sub-pixel for display; and the first colorsub-pixel block 111, the second color sub-pixel block 112 and the thirdcolor sub-pixel block 113 in the first virtual rectangle 110 mayconstitute a pixel unit for color display. Of course, the embodiment ofthe present disclosure includes, but is not limited thereto, and thefirst color sub-pixel block 111, the second color sub-pixel block 112and the third color sub-pixel block 113 may be respectively combinedwith an adjacent same color sub-pixel into one sub-pixel for display.

For example, in some examples, the first color sub-pixel block is asensitive color sub-pixel. Because sensitivity of human eyes to colorsis varied, upon adjacent sensitive color sub-pixels being closer to eachother, it is likely that the adjacent two sensitive color sub-pixels aredifficult to distinguish and are visually combined into one by the humaneyes due to a closer distance between the adjacent sensitive colorsub-pixels. Thus, the pixel arrangement structure can improvedistribution uniformity of sensitive color sub-pixels, so as to improvevisual resolution and further improve display quality. It should benoted that, upon a red, green and blue (RGB) mode being used in thepixel arrangement structure, the above-described sensitive color isgreen.

For example, in some examples, the first color sub-pixel block is agreen sub-pixel, the second color sub-pixel block is a red sub-pixel,and the third color sub-pixel block is a blue sub-pixel; or, the firstcolor sub-pixel block is a green sub-pixel, the second color sub-pixelblock is a blue sub-pixel, and the third color sub-pixel block is a redsub-pixel. Of course, the embodiment of the present disclosure includes,but is not limited thereto.

For example, in some examples, a distance between an edge of the firstcolor sub-pixel block 111 that is close to the first edge 1101 and thefirst edge 1101 is ⅓ to 5/12 of the length of the second edge 1102.Therefore, a distance between two closest edges of adjacent two firstcolor sub-pixel blocks is larger than ⅙ of the length of the secondedge.

For example, in some examples, a distance between the center of thefirst color sub-pixel block and the first edge is 9/16 to 11/16 of thelength of the second edge. Thus, distribution uniformity of first colorsub-pixel blocks can be further improved, so as to further improvevisual resolution and further improve display quality.

For example, in some examples, the distance between the center of thefirst color sub-pixel block and the first edge is ⅝ of the length of thesecond edge. Thus, distribution uniformity of first color sub-pixelblocks can be further improved, so as to further improve visualresolution and further improve display quality.

For example, in some examples, the above-described virtual rectangle maybe a square, that is to say, the first edge and the second edge areequal in length.

For example, in some examples, as illustrated by FIG. 4, each of theplurality of minimum repeating regions 100 further includes a secondvirtual rectangle 120, a third virtual rectangle 130 and a fourthvirtual rectangle 140. The first virtual rectangle 110, the secondvirtual rectangle 120, the third virtual rectangle 130 and the fourthvirtual rectangle 140 form a 2*2 matrix in an edge-sharing manner toconstitute one of the plurality of minimum repeating regions 100; thesecond virtual rectangle 120 shares the first edge 1101 with the firstvirtual rectangle, and is mirror-symmetrical to the first virtualrectangle with respect to the first edge 1101; the first virtualrectangle 110 coincides with the third virtual rectangle 130 by shiftinga distance of a length of a diagonal line of the first virtual rectangle110 along the diagonal line; the third virtual rectangle 130 includes athird edge 1303 extending in the first direction, and the fourth virtualrectangle 140 shares the third edge 1303 with the third virtualrectangle 130, and is mirror-symmetrical to the third virtual rectangle130 with respect to the third edge 1303. It should be noted that, thefirst virtual rectangle, the second virtual rectangle, the third virtualrectangle and the fourth virtual rectangle are closely arranged to formthe minimum repeating region having a rectangular shape. It should benoted that, the above-described word “coincide” refers to that threesub-pixel blocks in the third virtual rectangle have same shapes andpositions as the three sub-pixel blocks in the first virtual rectangletranslated along the diagonal line of the first virtual rectangle forthe length of the diagonal line. Here, the word “coincide” only refersto that the pixel blocks coincide with each other, while otherstructures may be different or the same. In addition, theabove-described word “coincide” refers to that approximate positions,shapes and sizes only have to be similar; and in some cases, the shapesmay be slightly different for the sake of wiring or opening, forexample, opening at different positions. Furthermore, correspondingsub-pixels or sub-pixel blocks or other components in virtual rectanglesonly need to have at least 70% of an area overlapped so as to be deemedto “coincide” as described in the present disclosure; and correspondingsub-pixels or sub-pixel blocks in virtual rectangles only need to haveat least 70% of an area overlapped after a mirroring operation so as tobe deemed to “be mirror-symmetrical” as described in the presentdisclosure.

In the pixel arrangement structure provided by this embodiment, thesecond virtual rectangle is mirror-symmetrical to the first virtualrectangle, a structure of the third virtual rectangle is the same as astructure of the first virtual rectangle translated along the diagonalline of the first virtual rectangle, the fourth virtual rectangle ismirror-symmetrical to the third virtual rectangle; a distance between acenter of a first color sub-pixel block in the third virtual rectangleand the third edge is ½ to ¾ of the length of the second edge, and adistance between a center of a first color sub-pixel block in the fourthvirtual rectangle and the third edge is ½ to ¾ of the length of thesecond edge, so a distance between the center of the first colorsub-pixel block in the third virtual rectangle and the center of thefirst color sub-pixel block in the fourth virtual rectangle is greaterthan ½ of the length of the second edge, which, thus, can avoid a casewhere adjacent two first color sub-pixel blocks are difficult todistinguish and are visually combined into one by human eyes due to acloser distance between the adjacent first color sub-pixel blocks, sothat granular sensation generated thereby can be avoided. Thus, thepixel arrangement structure can improve distribution uniformity of firstcolor sub-pixel blocks, so as to improve visual resolution and alsoimprove display quality.

In addition, as illustrated by FIG. 4, the distance between the centerof the first color sub-pixel block in the first virtual rectangle andthe first edge is ½ to ¾ of the length of the second edge, the distancebetween the center of the first color sub-pixel block in the fourthvirtual rectangle and the third edge is ½ to ¾ of the length of thesecond edge, and a slope between a connecting line between the firstcolor sub-pixel block in the first virtual rectangle and the first colorsub-pixel block in the fourth virtual rectangle is relatively low; soupon pixel units belonging to a same row (for example, the first virtualrectangle and the fourth virtual rectangle) collectively displaying astraight line, because the slope of the connection line between thefirst color sub-pixel block in the first virtual rectangle and the firstcolor sub-pixel block in the fourth virtual rectangle is relatively low,a fluctuation range of the first color sub-pixel block in the firstvirtual rectangle and the first color sub-pixel block in the fourthvirtual rectangle is relatively small, which, thus, can avoid a casewhere two straight lines displayed by adjacent rows are difficult todistinguish and are visually combined into one by human eyes due tomutual occlusion of the two straight lines resulted from a relativelylarge fluctuation range. Thus, the pixel arrangement structure canimprove visual resolution.

In addition, in the pixel arrangement structure, the second virtualrectangle is mirror-symmetrical to the first virtual rectangle, thestructure of the third virtual rectangle is the same as the structure ofthe first virtual rectangle translated along the diagonal line of thefirst virtual rectangle, and the fourth virtual rectangle ismirror-symmetrical to the third virtual rectangle, which can improvedistribution uniformity of sub-pixels in the pixel arrangementstructure, and can also avoid formation of a color line. In addition,within the minimum repeating region 100, there is no color mixingproblem in same color sub-pixels, and a second color sub-pixel block 112in the first virtual rectangle 110 is closer to a second color sub-pixelblock 112 in the second virtual rectangle 120, so upon the pixelarrangement structure being applied to an organic light-emitting displaydevice, a light-emitting layer of the second color sub-pixel block 112in the first virtual rectangle 110 and a light-emitting layer of thesecond color sub-pixel block 112 in the second virtual rectangle 120 maybe formed through the same opening on a mask plate; similarly, upon thepixel arrangement structure being applied to an organic light-emittingdisplay device, because a third color sub-pixel block 113 in the firstvirtual rectangle 110 is closer to a third color sub-pixel block 113 inthe second virtual rectangle 120, a light-emitting layer of the thirdcolor sub-pixel block 113 in the first virtual rectangle 110 and alight-emitting layer of the third color sub-pixel block 113 in thesecond virtual rectangle 120 may also be formed through the same openingon a mask.

For example, in some examples, the first color sub-pixel block 111, thesecond color sub-pixel block 112 and the third color sub-pixel block 113in the second virtual rectangle 120 may constitute one pixel unit forcolor display; the first color sub-pixel block 111, a second colorsub-pixel block 112 and a third color sub-pixel block 113 in the thirdvirtual rectangle 130 may constitute one pixel unit for color display;and the first color sub-pixel block 111, a second color sub-pixel block112 and a third color sub-pixel block 113 in the fourth virtualrectangle 140 may constitute one pixel unit for color display.

In the pixel arrangement structure provided by this embodiment, becausethe second color sub-pixel block and the third color sub-pixel block aredistributed on two sides of the perpendicular bisector of the firstedge, and the center of the first color sub-pixel block is located onthe perpendicular bisector of the first edge and the distance betweenthe center of the first color sub-pixel block and the first edge whichis ½ to ¾ of the length of the second edge; a distance between centersof adjacent two first color sub-pixel blocks is larger than ½ of thelength of the second edge, which, thus, can avoid a case where theadjacent two first color sub-pixel blocks are difficult to distinguishand are visually combined into one by human eyes due to a closerdistance between the adjacent first color sub-pixel blocks, so thatgranular sensation generated thereby can be avoided. Thus, the pixelarrangement structure can improve distribution uniformity of first colorsub-pixel blocks, so as to improve visual resolution and also improvedisplay quality.

For example, in some examples, as illustrated by FIG. 4, within thefirst virtual rectangle 110, the second color sub-pixel block 112 andthe third color sub-pixel block 113 are respectively close to two endsof the first edge 1101. It should be noted that, according to theabove-described relationship of the second virtual rectangle, the thirdvirtual rectangle and the fourth virtual rectangle with the firstvirtual rectangle, a positional relationship between the second colorsub-pixel block and the third color sub-pixel block in the secondvirtual rectangle, the third virtual rectangle and the fourth virtualrectangle also change accordingly. For example, as illustrated by FIG.4, in the fourth virtual rectangle 140, a distance between the center ofthe first color sub-pixel block 111 and an upper edge of the fourthvirtual rectangle 140 (equivalent to the first edge 1101 in the firstvirtual rectangle 110) is ½ to ¾ of the length of the second edge.

For example, in some examples, as illustrated by FIG. 4, within thefirst virtual rectangle 110, edges of the second color sub-pixel block112 and the third color sub-pixel block 113 that are away from a centerof the first virtual rectangle 110 are located on the first edge, sothat space within the first virtual rectangle can be utilized to thegreatest extent. It should be noted that, according to theabove-described relationship of the second virtual rectangle, the thirdvirtual rectangle and the fourth virtual rectangle with the firstvirtual rectangle, the positional relationship between the second colorsub-pixel block and the third color sub-pixel block in the secondvirtual rectangle, the third virtual rectangle and the fourth virtualrectangle also change accordingly.

For example, in some examples, as illustrated by FIG. 4, shortestdistances among the first color sub-pixel block 111, the second colorsub-pixel block 112 and the third color sub-pixel block 113 are equal toone another. That is to say, a shortest distance between the first colorsub-pixel block 111 and the second color sub-pixel block 112, a shortestdistance between the first color sub-pixel block 111 and the third colorsub-pixel block 113, and a shortest distance between the second colorsub-pixel block 112 and the third color sub-pixel block 113 are equal toone another, so that process precision can be utilized to the greatestextent.

For example, in some examples, as illustrated by FIG. 4, the shape ofthe second color sub-pixel block 112 is the same as the shape of thethird color sub-pixel block 113, and the shape of the second colorsub-pixel block 112 and the shape of the third color sub-pixel block 113are symmetrical to each other with respect to a diagonal line of theshape of the first color sub-pixel block 111, which is located betweenright angles formed by a first connection line and a second connectionline. Thus, symmetry and uniformity of the pixel arrangement structuremay be further improved, so as to further improve display quality.

For example, in some examples, as illustrated by FIG. 4, the shape ofthe first color sub-pixel block 111 is a right-base-angle symmetricalpentagon; the right-base-angle symmetrical pentagon is symmetrical withrespect to the perpendicular bisector of the first edge 1101; and a baseof the right-base-angle symmetrical pentagon is parallel to the firstedge 1101 or is located on the first edge 1101, and is further away fromthe first edge 1101 than a vertex of the right-base-angle symmetricalpentagon in a direction perpendicular to the first edge 1101. Asillustrated by FIG. 4, two oblique edges of the first color sub-pixelblock 111 may be provided respectively opposite to the second colorsub-pixel block 112 and the third color sub-pixel block 113, so that ina case where process precision is constant, that is to say, in a casewhere distances from the first color sub-pixel block 111 respectively tothe second color sub-pixel block 112 and the third color sub-pixel block113 are constant, an area of the first color sub-pixel block 111 isincreased. Thus, the pixel arrangement structure can improve autilization ratio of space within the first virtual rectangle. It shouldbe noted that, the above-described expression “be provided opposite”refers to that the two oblique edges of the first color sub-pixel block111 respectively face the second color sub-pixel block 112 and the thirdcolor sub-pixel block 113.

For example, in some examples, as illustrated by FIG. 4, the shapes ofthe second color sub-pixel block 112 and the third color sub-pixel block113 are both right-base-angle symmetrical pentagons; theright-base-angle symmetrical pentagons are symmetrical to each otherwith respect to the perpendicular bisector of the first edge; and basesof the right-base-angle symmetrical pentagons are parallel to the firstedge 1101 or are located on the first edge 1101, and are closer to thefirst edge 1101 than the vertexes of the right-base-angle symmetricalpentagons in the direction perpendicular to the first edge 1101. Asillustrated by FIG. 4, oblique edges of the second color sub-pixel block112 and the third color sub-pixel block 113 that are close to the firstcolor sub-pixel block 111 may be respectively opposite to the firstcolor sub-pixel block 111, so that in a case where process precision isconstant, that is to say, in the case where the distances from the firstcolor sub-pixel block 111 respectively to the second color sub-pixelblock 112 and the third color sub-pixel block 113 are constant, areas ofthe second color sub-pixel block 112 and the third color sub-pixel block113 are increased. Thus, the pixel arrangement structure can improve theutilization ratio of the space within the first virtual rectangle.

For example, a distance between adjacent edges of two first colorsub-pixel blocks is greater than or equal to 12 microns, or greater thanor equal to 14 microns. As illustrated by FIG. 4, two first colorsub-pixel blocks in each minimum repeating region, for example, refer toone first color sub-pixel block in a fourth virtual rectangle 140 andone first color sub-pixel block in a third virtual rectangle 130.Adjacent edges of the two first color sub-pixel blocks are just an edgeof a lower side of the upper first color sub-pixel block and an edge ofan upper side of the lower first color sub-pixel block. Theabove-described distance between the two first color sub-pixel blockscan be set to different numerical values according to differentresolution conditions. For example, the distance between the adjacentedges of the two first color sub-pixel blocks is greater than or equalto 12 microns in a case of quarter full high definition resolution, andis greater than or equal to 14 microns in a case of full high definitionresolution.

It should be noted that, although the shapes of the sub-pixel blocksshown in the drawings include a corner strictly formed by two straightlines, in some embodiments, the shapes of the sub-pixel blocks may berounded shapes, that is, corners of the shapes of the sub-pixel blocksare rounded. For example, the light emitting layer can be formed by anevaporation process through a mask, and therefore, a corner portionthereof can be a rounded shape.

FIG. 5 is a schematic diagram of another pixel arrangement structureprovided by an embodiment of the present disclosure. As illustrated byFIG. 5, shapes of a second color sub-pixel block 112 and a third colorsub-pixel block 113 are both right-angled trapezoids; bases of theright-angled trapezoids are perpendicular to a first edge 1101; and adistance between a right-angle edge of the right-angled trapezoid andthe first edge 1101 is smaller than a distance between an oblique edgeof the right-angled trapezoid and the first edge 1101. As illustrated byFIG. 5, the oblique edges of the second color sub-pixel block 112 andthe third color sub-pixel block 113 may be respectively opposite to afirst color sub-pixel block 111, so that in a case where processprecision is constant, that is to say, in a case where distances fromthe first color sub-pixel block 111 respectively to the second colorsub-pixel block 112 and the third color sub-pixel block 113 areconstant, areas of the second color sub-pixel block 112 and the thirdcolor sub-pixel block 113 are increased. Thus, the pixel arrangementstructure can improve a utilization ratio of space within a firstvirtual rectangle. Moreover, because the shapes of the second colorsub-pixel block 112 and the third color sub-pixel block 113 are bothright-angled trapezoids: as compared with a case where the shapes of thesecond color sub-pixel block 112 and the third color sub-pixel block 113are both right-base-angle symmetrical pentagons, acute angle portions190 of the second color sub-pixel block 112 and the third colorsub-pixel block 113 may further increase the areas of the second colorsub-pixel block 112 and the third color sub-pixel block 113, so as tofurther improve the utilization ratio of the space within the firstvirtual rectangle.

For example, in some examples, as illustrated by FIG. 5, a shape of thefirst color sub-pixel block 111 is a right-base-angle symmetricalpentagon; the right-base-angle symmetrical pentagon is symmetrical withrespect to a perpendicular bisector of the first edge; a base of theright-base-angle symmetrical pentagon is parallel to the first edge1101, and is further away from the first edge than a vertex of theright-base-angle symmetrical pentagon in a direction perpendicular tothe first edge; the right-base-angle symmetrical pentagon includes athird oblique edge 193 and a fourth oblique edge 194 passing through thevertex of the right-base-angle symmetrical pentagon; the third obliqueedge 193 and the fourth oblique edge 194 are equal in length; the thirdoblique edge 193 of the first color sub-pixel block 111 and the obliqueedge of the second color sub-pixel block 112 are parallel to each otherand have a spacing of a fifth distance; and the fourth oblique edge 194of the first color sub-pixel block 111 and the oblique edge of the thirdcolor sub-pixel block are parallel to each other and have a spacing of asixth distance.

For example, in some examples, as illustrated by FIG. 5, within a firstvirtual rectangle 110 and a second virtual rectangle 120, third colorsub-pixel blocks 113 are closer to a center of a minimum repeatingregion 100 than second color sub-pixel blocks 112; within a thirdvirtual rectangle 130 and a fourth virtual rectangle 140, second colorsub-pixel blocks 112 are closer to the center of the minimum repeatingregion 100 than third color sub-pixel blocks 113; a third colorsub-pixel block 113 in the first virtual rectangle 110 is adjacent to asecond color sub-pixel block 112 in the fourth virtual rectangle 140; athird color sub-pixel block 113 in the second virtual rectangle 120 isadjacent to a second color sub-pixel block 112 in the third virtualrectangle 130; a spacing between an acute angle portion 190 of the thirdcolor sub-pixel block 113 in the first virtual rectangle 110 and anacute angle portion 190 of the second color sub-pixel block 112 in thefourth virtual rectangle 140 is a seventh distance; and a spacingbetween an acute angle portion 190 of the third color sub-pixel block113 in the second virtual rectangle 120 and an acute angle portion 190of the second color sub-pixel block 112 in the third virtual rectangle130 is an eighth distance.

For example, in some examples, as illustrated by FIG. 5, the fifthdistance, the sixth distance, the seventh distance and the eighthdistance are all equal to one another.

For example, as illustrated in FIG. 5, a distance between a third colorsub-pixel block and a first color sub-pixel block that are adjacent toeach other is equal to a distance between a third color sub-pixel blockand a second color sub-pixel block that are adjacent to each other, bothbeing distance d. In some examples, a distance between a first colorsub-pixel block and a second color sub-pixel block that are adjacent toeach other is also equal to the above-described distance d.

For example, in some examples, as illustrated by FIG. 5, the secondcolor sub-pixel block and the third color sub-pixel block may also havean asymmetrical shape which, for example, is asymmetrical with respectto a straight line passing through its center in a second direction.

FIG. 6 is a schematic diagram of another pixel arrangement structureprovided by an embodiment of the present disclosure. As illustrated byFIG. 6, shapes of a second color sub-pixel block 112 and a third colorsub-pixel block 113 are both right-base-angle pentagons; bases of theright-base-angle pentagons are parallel to a first edge 1101 or arelocated on the first edge 1101, and are closer to the first edge 1101than vertexes of the right-base-angle pentagons in a directionperpendicular to the first edge 1101; the right-base-angle pentagonincludes a first oblique edge 191 and a second oblique edge 192 passingthrough the vertex; the first oblique edge 191 is opposite to a firstcolor sub-pixel block 111; and a length of the first oblique edge 191 islarger than a length of the second oblique edge 192. For example, afirst oblique edge 191 of the second color sub-pixel block 112 isopposite to the first color sub-pixel block 111, and a first obliqueedge 191 of the third color sub-pixel block 113 is opposite to the firstcolor sub-pixel block 111, so that in a case where process precision isconstant, that is to say, in a case where distances from the first colorsub-pixel block 111 respectively to the second color sub-pixel block 112and the third color sub-pixel block 113 are constant, areas of thesecond color sub-pixel block 112 and the third color sub-pixel block 113are increased, so as to improve a utilization ratio of space within afirst virtual rectangle. Moreover, because the shapes of the secondcolor sub-pixel block 112 and the third color sub-pixel block 113 areboth right-base-angle pentagons: as compared with a case where theshapes of the second color sub-pixel block 112 and the third colorsub-pixel block 113 are both right-base-angle symmetrical pentagons,regions where the second oblique edges 192 of the second color sub-pixelblock 112 and the third color sub-pixel block 113 are located mayfurther increase the areas of the second color sub-pixel block 112 andthe third color sub-pixel block 113, so as to further improve theutilization ratio of the space within the first virtual rectangle; andas compared with a case where the shapes of the second color sub-pixelblock 112 and the third color sub-pixel block 113 are both right-angledtrapezoids, the second oblique edges 192 of the second color sub-pixelblock 112 and the third color sub-pixel block 113 can have a fabricationdifficulty reduced, and in case where a technological level isrelatively low, the shapes of the second color sub-pixel block and thethird color sub-pixel block may be right-base-angle pentagons.

For example, a ratio of a length of an orthographic projection of thefirst oblique edge 191 in the first direction and a length of anorthographic projection of the second oblique edge 192 in the firstdirection is in a range of 2-6. Thus, a brightness center of the thirdcolor sub-pixel block is closer to the first color sub-pixel block, soas to reduce the risk of color separation.

For example, in some examples, as illustrated by FIG. 6, a shape of thefirst color sub-pixel block 111 is a right-base-angle symmetricalpentagon; the right-base-angle symmetrical pentagon is symmetrical withrespect to a line parallel to the second direction and passing throughthe first edge; a base of the right-base-angle symmetrical pentagon isparallel to the first edge or is located on the first edge, and isfurther away from the first edge than the vertex of the right-base-anglesymmetrical pentagon in the direction perpendicular to the first edge;the right-base-angle symmetrical pentagon includes a third oblique edge193 and a fourth oblique edge 194 passing through the vertex of theright-base-angle symmetrical pentagon; the third oblique edge 193 andthe fourth oblique edge 194 are equal in length; the third oblique edge193 of the first color sub-pixel block 111 and the first oblique edge191 of the second color sub-pixel block 112 are parallel to each otherand have a spacing of a first distance; and the fourth oblique edge 194of the first color sub-pixel block 111 and the first oblique edge 191 ofthe third color sub-pixel block are parallel to each other and have aspacing of a second distance. It should be noted that, theabove-described case of “being parallel” includes a case of beingsubstantially parallel; and the above-described distance refers to aminimum distance, or a distance between two intersection points formedas a line connecting centers of two sub-pixels respectively intersectswith two closest edges of the two sub-pixels.

For example, in some examples, as illustrated by FIG. 6, within thefirst virtual rectangle 110 and a second virtual rectangle 120, thirdcolor sub-pixel blocks 113 are closer to a center of a minimum repeatingregion 100 than second color sub-pixel blocks 112; within a thirdvirtual rectangle 130 and a fourth virtual rectangle 140, second colorsub-pixel blocks 112 are closer to the center of the minimum repeatingregion 100 than third color sub-pixel blocks 113; the third colorsub-pixel block 113 in the first virtual rectangle 110 is adjacent to asecond color sub-pixel block 112 in the fourth virtual rectangle 140; athird color sub-pixel block 113 in the second virtual rectangle 120 isadjacent to a second color sub-pixel block 112 in the third virtualrectangle 130; the second oblique edge 192 of the third color sub-pixelblock 113 in the first virtual rectangle 110 and a second oblique edge192 of the second color sub-pixel block 112 in the fourth virtualrectangle 140 are parallel to each other and have a spacing of a thirddistance; and a second oblique edge 192 of the third color sub-pixelblock 113 in the second virtual rectangle 120 and a second oblique edge192 of the second color sub-pixel block 112 in the third virtualrectangle 130 are parallel to each other and have a spacing of a fourthdistance.

For example, in some examples, the first distance, the second distance,the third distance and the fourth distance as described above are allequal to one another, so that a utilization ratio of process precisioncan be improved.

FIG. 7A is a schematic diagram of another pixel arrangement structureprovided by an embodiment of the present disclosure. FIG. 7A shows twominimum repeating regions 100; as illustrated by FIG. 7A, within thesame minimum repeating region 100, a second color sub-pixel block 112 ofa first virtual rectangle 110 and a second color sub-pixel block 112 ofa second virtual rectangle 120 are combined into a same sub-pixel, i.e.,a second unitary sub-pixel block 1128; within two minimum repeatingregions 100 adjacent to each other in a second direction, the adjacenttwo minimum repeating regions 100 in the second direction include afirst minimum repeating region 1001 and a second minimum repeatingregion 1002 sequentially arranged in the second direction; and a secondcolor sub-pixel block 112 of a fourth virtual rectangle 140 of the firstminimum repeating region 1001 and a second color sub-pixel block 112 ofa third virtual rectangle 130 of the second minimum repeating region1002 are combined into a same sub-pixel, i.e., i.e., a second unitarysub-pixel block 1128. Thus, combination of second color sub-pixel blocksinto a same sub-pixel can reduce difficulty in manufacturing process ofthe second color sub-pixel blocks. In addition, upon the pixelarrangement structure being used in a display panel, it may be driven byusing a Sub-pixel Rendering (SPR) algorithm to implement virtualdisplay.

In some examples, in each of the second unitary sub-pixel block, adistance between centers of the two second color sub-pixel blocks is0.1-0.5 times of a length of the first edge, so as to reduce the risk ofcolor separation.

In some examples, in each of the second unitary sub-pixel block, adistance between centers of the two second color sub-pixel blocks is0.1-0.35 times of a length of the first edge, so as to reduce the riskof color separation.

For example, in each of the second unitary sub-pixel block, the distancebetween centers of the two second color sub-pixel blocks is 0.2-0.3times (for example, 0.27 times) of the length of the first edge, so asto further reduce the risk of color separation.

For example, a length a length-width ratio of the second unitarysub-pixel block is 1-8, so as to further reduce the risk of colorseparation. It should be noted that, the length-width ratio is a ratioof a length of a shape to a width of the shape. Besides, a length of theshape can be a size of the shape in the second direction, and a width ofthe shape can be a size of the shape in the first direction. Or, alength of the shape can be a largest size of the shape, and a width ofthe shape can be a smallest size of the shape.

For example, a length-width ratio of the second unitary sub-pixel blockis 2-3 (for example, 2.6), so as to further reduce the risk of colorseparation.

It should be noted that, the second color sub-pixel block of the firstvirtual rectangle and the second color sub-pixel block of the secondvirtual rectangle within the same minimum repeating region that arecombined into a same sub-pixel, or the second color sub-pixel block ofthe fourth virtual rectangle of the first minimum repeating region andthe second color sub-pixel block of the third virtual rectangle of thesecond minimum repeating region that are combined into a same sub-pixelas described above are driven to emit light as a same sub-pixel. That isto say, the above-described second color sub-pixel blocks located indifferent virtual rectangles that are combined into a same sub-pixelserve only as a portion of one sub-pixel, and at this time, a center ofthe integrated sub-pixel is located on a first edge or on a shared edgeof the adjacent two minimum repeating regions in the second direction.

For example, upon the second color sub-pixel block having a shape ofright-base-angle symmetrical pentagon, the second unitary sub-pixelblock has a shape of hexagon.

For example, in some examples, as illustrated by FIG. 7A, within thesame minimum repeating region 100, a third color sub-pixel block 113 ofthe first virtual rectangle 110 and a third color sub-pixel block 113 ofthe second virtual rectangle 120 are combined into a same sub-pixel,i.e., a third unitary sub-pixel block 1138; within the two minimumrepeating regions 100 adjacent to each other in the second direction,the adjacent two minimum repeating regions 100 in the second directioninclude the first minimum repeating region 1001 and the second minimumrepeating region 1002 sequentially arranged in the second direction; anda third color sub-pixel block 113 of the fourth virtual rectangle 140 ofthe first minimum repeating region 1001 and a third color sub-pixelblock 113 of the third virtual rectangle 130 of the second minimumrepeating region 1002 are combined into a same sub-pixel, i.e., a thirdunitary sub-pixel block 1138. Thus, combination of third color sub-pixelblocks into a same sub-pixel can reduce a difficulty in manufacturingprocess of the third color sub-pixel blocks. In addition, when the pixelarrangement structure is used in a display panel, it may be driven byusing a Sub-pixel Rendering (SPR) algorithm to implement virtualdisplay.

It should be noted that, the third color sub-pixel block of the firstvirtual rectangle and the third color sub-pixel block of the secondvirtual rectangle within the same minimum repeating region that arecombined into a same sub-pixel, or the third color sub-pixel block ofthe fourth virtual rectangle of the first minimum repeating region andthe third color sub-pixel block of the third virtual rectangle of thesecond minimum repeating region that are combined into a same sub-pixelas described above are driven to emit light as a same sub-pixel. That isto say, the above-described third color sub-pixel blocks located indifferent virtual rectangles that are combined into a same sub-pixelserve only as a portion of one sub-pixel, and at this time, a center ofthe integrated sub-pixel is located on the first edge or on the sharededge of the adjacent two minimum repeating regions in the seconddirection.

In addition, within the same one of the plurality of minimum repeatingregions 100, the second color sub-pixel block 112 of the first virtualrectangle 110 and the second color sub-pixel block 112 of the secondvirtual rectangle 120 may not be combined into a same sub-pixel; withintwo adjacent ones of the plurality of minimum repeating regions 100 inthe second direction, the two adjacent ones of the plurality of minimumrepeating regions 100 in the second direction include a first minimumrepeating region 1001 and a second minimum repeating region 1002sequentially arranged in the second direction; and the second colorsub-pixel block 112 of the fourth virtual rectangle 140 of the firstminimum repeating region 1001 and the second color sub-pixel block 112of the third virtual rectangle 130 of the second minimum repeatingregion 1002 may not be combined into a same sub-pixel. At this time, thesecond color sub-pixel block 112 of the first virtual rectangle 110 andthe second color sub-pixel block 112 of the second virtual rectangle 120are respectively driven to emit light as two second color sub-pixelblocks, and may share a same single color pattern region in a sub-pixelpatterning process. The second color sub-pixel block 112 of the fourthvirtual rectangle 140 of the first minimum repeating region 1001 and thesecond color sub-pixel block 112 of the third virtual rectangle 130 ofthe second minimum repeating region 1002 are respectively driven to emitlight as two second color sub-pixel blocks, and may share a same singlecolor pattern region in a sub-pixel patterning process.

In addition, within the same minimum repeating region 100, the thirdcolor sub-pixel block 113 of the first virtual rectangle 110 and thethird color sub-pixel block 113 of the second virtual rectangle 120 maynot be combined into a same sub-pixel; within the two minimum repeatingregions 100 adjacent to each other in the second direction, the adjacenttwo minimum repeating regions 100 in the second direction include thefirst minimum repeating region 1001 and the second minimum repeatingregion 1002 sequentially arranged in the second direction; and the thirdcolor sub-pixel block 113 of the fourth virtual rectangle 140 of thefirst minimum repeating region 1001 and the third color sub-pixel block113 of the third virtual rectangle 130 of the second minimum repeatingregion 1002 may not be combined into a same sub-pixel. At this time, thethird color sub-pixel block 113 of the first virtual rectangle 110 andthe third color sub-pixel block 113 of the second virtual rectangle 120are respectively driven to emit light as two third color sub-pixelblocks, and may share a same single color pattern region in a sub-pixelpatterning process. The third color sub-pixel block 113 of the fourthvirtual rectangle 140 of the first minimum repeating region 1001 and thethird color sub-pixel block 113 of the third virtual rectangle 130 ofthe second minimum repeating region 1002 are respectively driven to emitlight as two third color sub-pixel blocks, and may share a same singlecolor pattern region in a sub-pixel patterning process. For example, insome examples, as illustrated by FIG. 7A, within the same minimumrepeating region 100, a first color sub-pixel block 111 of the thirdvirtual rectangle 130 and a first color sub-pixel block 111 of thefourth virtual rectangle 140 share a same single color pattern region ina sub-pixel patterning process. For example, when the pixel arrangementstructure is applied to an organic light-emitting display device, thesub-pixel patterning process includes an evaporation process; and alight-emitting layer of the first color sub-pixel block 111 of the thirdvirtual rectangle 130 and a light-emitting layer of the first colorsub-pixel block 111 of the fourth virtual rectangle 140 may be formedthrough a same opening on a mask. Of course, the above-describedsub-pixel patterning process includes, but is not limited to, anevaporation process, and may also include printing, a color filterpatterning process, and so on. Thus, the first color sub-pixel block 111of the third virtual rectangle 130 and the first color sub-pixel block111 of the fourth virtual rectangle 140 share a same single colorpattern region in a sub-pixel patterning process such as printing and acolor filter patterning process.

For example, as illustrated by FIG. 5, FIG. 6, and FIG. 7B, a shape ofat least one of the second unitary sub-pixel block 1128 and the thirdunitary sub-pixel block 1138 includes a parallel edge group 410, theparallel edge group 410 includes two parallel edges 410A, 410B, whichare both approximately parallel to one of the first direction and thesecond direction, and the two parallel edges 410A, 410B have differentlengths.

For example, as illustrated by FIG. 5, FIG. 6, and FIG. 7B, the shape ofat least one of the second unitary sub-pixel block 1128 and the thirdunitary sub-pixel block 1138 is approximately symmetrical with respectto a line extending in the other one of the first direction and thesecond direction.

For example, as illustrated by FIG. 6 and FIG. 7B, a shape of at leastone of the second unitary sub-pixel block 1128 and the third unitarysub-pixel block 1138 includes a hexagon, the hexagon includes a paralleledge group 410 including two parallel edges 410A, 410B, a first oppositeedge group 420 including two opposite edges 420A, 420B, and a secondopposite edge group 430 including two opposite edges 430A, 430B, the twoopposite edges 420A, 420B in the first opposite edge group 420 aredisposed opposite to each other, the two opposite edges 430A, 430B inthe second opposite edge group 430 are disposed opposite to each other,and the two parallel edges 410A, 410B in the parallel edge group 410have different lengths.

It is to noted that, the opposite edges are edges which are disposedopposite to each other; the opposite edges are not directly adjacent toeach other; and the opposite edges may be parallel to each other, or anincluded angle between extending lines of the opposite edges is smallerthan 90 degrees (for example, smaller than 45 degrees). For example,with regard to a hexagon, in a clockwise direction, a first edge, asecond edge, a third edge, a fourth edge, a fifth edge, and a sixth edgeare sequentially arranged; in this case, the first edge and the fourthedge are the opposite edges, the second edge and the fifth edge are theopposite edges, the third edge and the sixth edge are the oppositeedges. For another example, with regard to octagon, in a clockwisedirection, a first edge, a second edge, a third edge, a fourth edge, afifth edge, a sixth edge, a seventh edge, an eighth edge, a ninth edge,and a tenth edge are sequentially arranged; in this case, the first edgeand the fifth edge are the opposite edges, the second edge and the sixthedge are the opposite edges, the third edge and the seventh edge are theopposite edges, and the fourth edge and the eighth edge are the oppositeedges.

For example, as illustrated by FIG. 6 and FIG. 7B, the hexagon issymmetrical with respect to a line extending in the first direction.

In some examples, within the same one of the plurality of minimumrepeating regions 100, the two parallel edges in the parallel edge groupof at least one of the second unitary sub-pixel block 1128 and the thirdunitary sub-pixel block 1138 in the first virtual rectangle 110 and thesecond virtual rectangle 120 are approximately parallel to the seconddirection, one of the two parallel edges in the parallel edge groupwhich is close to a center line passing through a center of the firstcolor sub-pixel block 111 in the first virtual rectangle 110 is a firstparallel edge 410A, and one of the two parallel edges in the paralleledge group which is away from the center line passing through the centerline of the first color sub-pixel block 111 in the first virtualrectangle is a second parallel edge 410B, a length of the first paralleledge 410A is smaller than a length of the second parallel edge 410B;within two adjacent ones of the plurality of minimum repeating regions100 in the second direction, the two adjacent ones of the plurality ofminimum repeating regions 100 comprise a first minimum repeating region1001 and a second minimum repeating region 1002 sequentially arranged inthe second direction; the two parallel edges in the parallel edge groupof the second unitary sub-pixel block 1128 and the third unitarysub-pixel block 1138 in the third virtual rectangle 130 of the firstminimum repeating region 1001 and the fourth virtual rectangle 140 ofthe second minimum repeating region 1002 are approximately parallel tothe second direction, one of the two parallel edges in the parallel edgegroup which is close to a center line passing through a center of thefirst color sub-pixel block 111 in the third virtual rectangle 130 ofthe first minimum repeating region 1001 is a first parallel edge 410A,and one of the two parallel edges in the parallel edge group which isaway from the center line passing through the center line of the firstcolor sub-pixel block 111 in the third virtual rectangle 130 of thefirst minimum repeating region 1001 is a second parallel edge 410B, alength of the first parallel edge 410A is smaller than a length of thesecond parallel edge 410B.

However, the embodiments of the present disclosure are not limitedthereto. Referring to FIG. 7D, the length of the first parallel edge410A can also be larger than the length of the second parallel edge410B.

For example, as illustrated by FIG. 6 and FIG. 7B, the two paralleledges 410A, 410B in the parallel edge group 410 are approximatelyparallel to the second direction, one of the two parallel edges 410A,410B in the parallel edge group 410 which is close to a center line 500passing through a center of the first color sub-pixel block and parallelto the second direction is a first parallel edge 410A, and one of thetwo parallel edges 410A, 410B in the parallel edge group 410 which isaway from the center line passing through the center line 500 of thefirst color sub-pixel block and parallel to the second direction is asecond parallel edge 410B, a length of the first parallel edge 410A issmaller than a length of the second parallel edge 410B. It should benoted that, the center line 500 can be a brightness line of the firstcolor sub-pixel block.

In some examples, a shape of the second unitary sub-pixel block and ashape of the third unitary sub-pixel block both include the hexagon;within the same one of the plurality of minimum repeating regions, adistance between the first parallel edge of the hexagon of the secondunitary sub-pixel block in the first virtual rectangle and the secondvirtual rectangle and the center line of the first color sub-pixel blockin the first virtual rectangle is smaller than a distance between thefirst parallel edge of the hexagon of the third unitary sub-pixel blockin the first virtual rectangle and the second virtual rectangle and thecenter line of the first color sub-pixel block in the first virtualrectangle, and a length of the first parallel edge of the hexagon of thesecond unitary sub-pixel block in the first virtual rectangle and thesecond virtual rectangle is smaller than a length of the first paralleledge of the hexagon of the third unitary sub-pixel block in the firstvirtual rectangle and the second virtual rectangle; or, a distancebetween the first parallel edge of the hexagon of the second unitarysub-pixel block in the first virtual rectangle and the second virtualrectangle and the center line of the first color sub-pixel block in thefirst virtual rectangle is larger than a distance between the firstparallel edge of the hexagon of the third unitary sub-pixel block in thefirst virtual rectangle and the second virtual rectangle and the centerline of the first color sub-pixel block in the first virtual rectangle,and a length of the first parallel edge of the hexagon of the secondunitary sub-pixel block in the first virtual rectangle and the secondvirtual rectangle is larger than a length of the first parallel edge ofthe hexagon of the third unitary sub-pixel block in the first virtualrectangle and the second virtual rectangle.

In some examples, within two adjacent ones of the plurality of minimumrepeating regions in the second direction, the two adjacent ones of theplurality of minimum repeating regions comprise a first minimumrepeating region and a second minimum repeating region sequentiallyarranged in the second direction; a distance between the first paralleledge of the hexagon of the second unitary sub-pixel block in the thirdvirtual rectangle of the first minimum repeating region and the fourthvirtual rectangle of the second minimum repeating region and the centerline of the first color sub-pixel block in the third virtual rectangleof the first minimum repeating region is smaller than a distance betweenthe first parallel edge of the hexagon of the third unitary sub-pixelblock in the third virtual rectangle of the first minimum repeatingregion and the fourth virtual rectangle of the second minimum repeatingregion and the center line of the first color sub-pixel block in thethird virtual rectangle of the first minimum repeating region, and alength of the first parallel edge of the hexagon of the second unitarysub-pixel block in the third virtual rectangle of the first minimumrepeating region and the fourth virtual rectangle of the second minimumrepeating region is smaller than a length of the first parallel edge ofthe hexagon of the third unitary sub-pixel block in the third virtualrectangle of the first minimum repeating region and the fourth virtualrectangle of the second minimum repeating region; or, a distance betweenthe first parallel edge of the hexagon of the second unitary sub-pixelblock in the third virtual rectangle of the first minimum repeatingregion and the fourth virtual rectangle of the second minimum repeatingregion and the center line of the first color sub-pixel block in thethird virtual rectangle of the first minimum repeating region is largerthan a distance between the first parallel edge of the hexagon of thethird unitary sub-pixel block in the third virtual rectangle of thefirst minimum repeating region and the fourth virtual rectangle of thesecond minimum repeating region and the center line of the first colorsub-pixel block in the third virtual rectangle of the first minimumrepeating region, and a length of the first parallel edge of the hexagonof the second unitary sub-pixel block in the third virtual rectangle ofthe first minimum repeating region and the fourth virtual rectangle ofthe second minimum repeating region is larger than a length of the firstparallel edge of the hexagon of the third unitary sub-pixel block in thethird virtual rectangle of the first minimum repeating region and thefourth virtual rectangle of the second minimum repeating region.

For example, as illustrated by FIG. 6 and FIG. 7B, a shape of the secondunitary sub-pixel block and a shape of the third unitary sub-pixel blockboth include the hexagon, a distance between the first parallel edge410A of the hexagon of the second unitary sub-pixel block 1128 and thecenter line 500 is smaller than a distance between the first paralleledge 410A of the hexagon of the third unitary sub-pixel block 1138 andthe center line 500, and a length of the first parallel edge 410A of thehexagon of the second unitary sub-pixel block 1128 is smaller than alength of the first parallel edge 410A of the hexagon of the thirdunitary sub-pixel block 1138. Thus, upon the second unitary sub-pixelblock emitting red light, the second unitary sub-pixel block can becloser to the center line 500, i.e., a brightness line of the firstcolor sub-pixel block, so as to reduce the grain feeling of verticalline, thus improving the display effect.

Certainly, the embodiments of the present disclosure include but are notlimited thereto. Referring to FIG. 7E, A distance between the firstparallel edge 410A of the hexagon of the second unitary sub-pixel block1128 and the center line can be larger than a distance between the firstparallel edge 410A of the hexagon of the third unitary sub-pixel block113 and the center line, and a length of the first parallel edge 410A ofthe hexagon of the second unitary sub-pixel block 1128 can be largerthan a length of the first parallel edge 410A of the hexagon of thethird unitary sub-pixel block 1138.

For example, as illustrated by FIG. 7C, a shape of the second unitarysub-pixel block 1128 and a shape of the third unitary sub-pixel block1138 both include the hexagon, the first parallel edge of the hexagon ofthe second unitary sub-pixel block in the first virtual rectangle 120and the second virtual rectangle 130 goes beyond the center line of thefirst color sub-pixel block 111 in the first virtual rectangle 110.Thus, upon the second unitary sub-pixel block emits red light, thesecond unitary sub-pixel block can be closer to the center line 500,i.e., a brightness line of the first color sub-pixel block, so as toreduce the grain feeling of vertical line, thus improving the displayeffect. However, the embodiments of the present disclosure include butare not limited thereto, the first parallel edge of the hexagon of thethird unitary sub-pixel block in the first virtual rectangle and thesecond virtual rectangle goes beyond the center line of the first colorsub-pixel block in the first virtual rectangle.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, the shape ofat least one of the second unitary sub-pixel block 1128 and the thirdunitary sub-pixel block 1138 includes a polygon, for example, a hexagon,the polygon includes two vertexes P1, P2 which have the largest distancein the second direction, and a line connecting the two vertexes P1, P2is approximately parallel to the second direction.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, in thepolygon of at least one of the second unitary sub-pixel block 1128 andthe third unitary sub-pixel block 1138, an area of a first portion 441located at a first side (for example, the left side) of the lineconnecting the two vertexes P1, P2 is different from an area of a secondportion 442 located at a second side (for example, the right side) ofthe line connection the two vertexes P1, P2.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, the firstportion 441 is located at a side close to the first color sub-pixelblock 111 located in the same virtual rectangle, and the second portion442 is located at a side away from the first color sub-pixel block 111located in the same virtual rectangle.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, a ratio ofthe area of the first portion 441 and the area of the second portion 442is in a range of 0-1. For example, a ratio of the area of the firstportion 441 to the area of the second portion 442 is in a range of 0-1;for another example, a ratio of the area of the second portion 442 andthe area of the first portion 441 is in a range of 0-1.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, a width ofthe first portion 441 in the first direction is different from a widthof the second portion 442 in the second direction.

For example, as illustrated by FIG. 2, FIG. 6 and FIG. 7B, a ratio ofthe width of the first portion 441 in the first direction and the widthof the second portion 442 in the second direction is 0.1-6.

For example, upon the third color sub-pixel block having a shape ofright-base-angle symmetrical pentagon, the third unitary sub-pixel blockhas a shape of hexagon.

In some examples, as illustrated by FIG. 7A, within the same one of theplurality of minimum repeating regions 100, a distance between a centerof the first color sub-pixel block 111 of the third virtual rectangle130 and a center of the first color sub-pixel block 111 of the fourthvirtual rectangle 140 is 0.2-0.9 times of the length of the first edge;within two adjacent ones of the plurality of minimum repeating regions100 in the second direction, the two adjacent ones of the plurality ofminimum repeating regions include a first minimum repeating region and asecond minimum repeating region sequentially arranged in the seconddirection; and a distance between a center of the first color sub-pixelblock 111 of the first virtual rectangle 110 of the first minimumrepeating region and a center of the first color sub-pixel block 111 ofthe second virtual rectangle 120 of the second minimum repeating regionis 0.2-0.9 times of the length of the first edge. Thus, the distancebetween two first color sub-pixel blocks in two adjacent rows isrelatively large, so as to reduce the sawtooth feeling of greenhorizontal line and grain feeling of vertical line, thus improving thedisplay effect.

In some examples, as illustrated by FIG. 7A, within the same one of theplurality of minimum repeating regions, a distance between a center ofthe first color sub-pixel block of the third virtual rectangle and acenter of the first color sub-pixel block of the fourth virtualrectangle is 0.5-0.7 times, for example, 0.59 times, of the length ofthe first edge; within two adjacent ones of the plurality of minimumrepeating regions in the second direction, the two adjacent ones of theplurality of minimum repeating regions include a first minimum repeatingregion and a second minimum repeating region sequentially arranged inthe second direction; and a distance between a center of the first colorsub-pixel block of the first virtual rectangle of the first minimumrepeating region and a center of the first color sub-pixel block of thesecond virtual rectangle of the second minimum repeating region is0.5-0.7 times, for example, 0.59 times, of the length of the first edge.Thus, the distance between two first color sub-pixel blocks in twoadjacent rows is relatively large, so as to further reduce the sawtoothfeeling of green horizontal line and grain feeling of vertical line,thus improving the display effect.

For example, as illustrated by FIG. 7A, within the same one of theplurality of minimum repeating regions 100, a distance between a centerof the first color sub-pixel block 111 of the first virtual rectangle110 and a center of the first color sub-pixel block 111 of the secondvirtual rectangle 120 is 1.1-1.8 times of the length of the first edge;within two adjacent ones of the plurality of minimum repeating regions100 in the second direction, the two adjacent ones of the plurality ofminimum repeating regions include a first minimum repeating region and asecond minimum repeating region sequentially arranged in the seconddirection; and a distance between a center of the first color sub-pixelblock 111 of the third virtual rectangle 130 of the first minimumrepeating region and a center of the first color sub-pixel block 111 ofthe fourth virtual rectangle 140 of the second minimum repeating regionis 1.1-1.8 times of the length of the first edge. Thus, the distancebetween two first color sub-pixel blocks in the same row is relativelysmall, so as to reduce the sawtooth feeling of green horizontal line andgrain feeling of vertical line, thus improving the display effect.

For example, as illustrated by FIG. 7A, within the same one of theplurality of minimum repeating regions, a distance between a center ofthe first color sub-pixel block of the first virtual rectangle and acenter of the first color sub-pixel block of the second virtualrectangle is 1.3-1.5 times, for example, 1.4 times, of the length of thefirst edge; within two adjacent ones of the plurality of minimumrepeating regions in the second direction, the two adjacent ones of theplurality of minimum repeating regions include a first minimum repeatingregion and a second minimum repeating region sequentially arranged inthe second direction; and a distance between a center of the first colorsub-pixel block of the third virtual rectangle of the first minimumrepeating region and a center of the first color sub-pixel block of thefourth virtual rectangle of the second minimum repeating region is1.3-1.5 times, for example, 1.4 times, of the length of the first edge.Thus, the distance between two first color sub-pixel blocks in the samerow is relatively small, so as to reduce the sawtooth feeling of greenhorizontal line and grain feeling of vertical line, thus improving thedisplay effect.

For example, in some examples, as illustrated by FIG. 7A, an organiclight-emitting layer of the first color sub-pixel block 111 of the thirdvirtual rectangle 130 and an organic light-emitting layer of the firstcolor sub-pixel block 111 of the fourth virtual rectangle 140 areevaporated through a same opening on a fine metal mask.

For example, in some examples, as illustrated by FIG. 7A, within the twominimum repeating regions 100 adjacent to each other in the seconddirection, the adjacent two minimum repeating regions 100 in the seconddirection include the first minimum repeating region 1001 and the secondminimum repeating region 1002 sequentially arranged in the seconddirection; and a first color sub-pixel block 111 of the first virtualrectangle 110 of the first minimum repeating region 1001 and a firstcolor sub-pixel block 111 of the second virtual rectangle 120 of thesecond minimum repeating region 1002 may share a same single colorpattern region in a sub-pixel patterning process. For example, when thepixel arrangement structure is applied to an organic light-emittingdisplay device, the sub-pixel patterning process includes an evaporationprocess; and a light-emitting layer of the first color sub-pixel block111 of the first virtual rectangle 110 of the first minimum repeatingregion 1001 and a light-emitting layer of the first color sub-pixelblock 111 of the second virtual rectangle 120 of the second minimumrepeating region 1002 may be formed through a same opening on the mask,that is to say, the first color sub-pixel block 111 of the first virtualrectangle 110 of the first minimum repeating region 1001 and the firstcolor sub-pixel block 111 of the second virtual rectangle 120 of thesecond minimum repeating region 1002 include the light-emitting layersformed through the same opening on the mask. Of course, theabove-described sub-pixel patterning process includes, but is notlimited to, an evaporation process, and may also include printing, acolor filter patterning process, and so on. Thus, the first colorsub-pixel block 111 of the first virtual rectangle 110 of the firstminimum repeating region 1001 and the first color sub-pixel block 111 ofthe second virtual rectangle 120 of the second minimum repeating region1002 share a same single color pattern region in a sub-pixel patterningprocess such as printing and a color filter patterning process.Therefore, combination of first color sub-pixel blocks into a samesub-pixel can reduce a process difficulty in fabricating the first colorsub-pixel block.

For example, in some examples, as illustrated by FIG. 7A, within thesame minimum repeating region 100, a distance between a center of thesecond color sub-pixel block 112 and a center of the third colorsub-pixel block 113 in the first virtual rectangle 110 ranges from 5/9to 7/9 of the length of the first edge, so that it can be ensured that adistance from the third color sub-pixel blocks 113 of the first virtualrectangle 110 and the second virtual rectangle 120 to second colorsub-pixel blocks 112 of a first virtual rectangle 110 and a secondvirtual rectangle 120 of an adjacent minimum repeating region in thefirst direction is sufficiently large, so that it is convenient to formthe first color sub-pixel block 111 of the third virtual rectangle 130and the first color sub-pixel block 111 of the fourth virtual rectangle140 within the same minimum repeating region 100 through a same openingon the mask, and to form the first color sub-pixel block 111 of thefirst virtual rectangle 110 of the first minimum repeating region 1001and the first color sub-pixel block 111 of the second virtual rectangle120 of the second minimum repeating region 1002 through a same openingon the mask, so as to reduce a difficulty in process.

In addition, as viewed from a relationship between respective virtualrectangles and the minimum repeating region of FIG. 7A, a step of theminimum repeating region in the first direction is approximately equalto edge lengths of two virtual rectangles, that is, the step of theminimum repeating region in the first direction is about 2 L. Asillustrated by FIG. 7A, the second color sub-pixel block and the thirdcolor sub-pixel block in the first virtual rectangle 110 and the secondcolor sub-pixel block and the third color sub-pixel block in the secondvirtual rectangle 120 may be combined into one second color sub-pixelblock and one third color sub-pixel block, which, plus one first colorsub-pixel block in the third virtual rectangle 130 and one first colorsub-pixel block in the fourth virtual rectangle 130, may form arepeating unit. That is to say, a size of the repeating unit in thefirst direction or a step of the repeating unit in the first directionis twice the length of the edge of the virtual rectangle in the firstdirection. If the virtual rectangle is a square, then the step of theminimum repeating unit in the first direction is approximately 2 L.

As can be seen from FIG. 7A, the second color sub-pixel block and thethird color sub-pixel block have elongated shapes, that is, elongatedshapes extending in the second direction. In addition, the second colorsub-pixel block and the third color sub-pixel block may also haveelliptical shapes. With respect to the second color sub-pixel block, ifit is divided into two portions (the two portions are, for example, thesecond color sub-pixel block located in the first virtual rectangle 110and the second color sub-pixel block located in the second virtualrectangle) by a center line along the first direction, then a distancebetween centers of the two second color sub-pixel blocks is less than0.3 L. In addition, a size of the second color sub-pixel block in thesecond direction is less than 0.6 L.

With respect to the second color sub-pixel block and the third colorsub-pixel block, a ratio of a size in the second direction to a size inthe first direction is γ, and γ>1. That is to say, the second colorsub-pixel block and the third color sub-pixel block have elongatedshapes extending in the second direction.

For example, the second color sub-pixel is a red sub-pixel, and thethird color sub-pixel is a blue sub-pixel. A lifetime of the redsub-pixel is usually longer than that of the blue sub-pixel. Therefore,an area of the red sub-pixel may be smaller than an area of the bluesub-pixel; however, a ratio of a size in the first direction to a sizein the second direction of the red sub-pixel cannot be too small; if itis too small, a marked difference between a lateral direction and alongitudinal direction may be affected.

For example, as illustrated by FIG. 7F and FIG. 7G, the first colorsub-pixel blocks 111 in virtual rectangles belonging to the same row arelocated in a first sub-pixel row 710, each of the plurality of minimumrepeating regions 100 includes two first sub-pixel rows 710, and asecond sub-pixel row 720 is provided between the two first sub-pixelrows 710, the second sub-pixel row 720 includes multiple second colorsub-pixel blocks 112 and multiple third color sub-pixel blocks 113alternately arranged in the first direction, and multiple firstsub-pixel rows 710 and multiple second sub-pixel rows 720 arealternately arranged in the second direction; the first color sub-pixelblocks 111 in the first sub-pixel row 710 are controlled by the same rowof pixel circuits 250 (for example, the anodes used for driving thefirst color sub-pixel blocks 111 in the first sub-pixel row 710 areelectrically connected the pixel circuits 250 of the same row), so as tobe controlled by one gate line 260, and the second color sub-pixelblocks 112 and the third color sub-pixel blocks 113 in the secondsub-pixel row 720 are also controlled by the same row of pixel circuits250 (for example, the anodes used for driving the second color sub-pixelblocks 112 and the third color sub-pixel blocks 113 in the secondsub-pixel row 720 are electrically connected the pixel circuits 250 ofthe same row), so as to be controlled by one gate line 260.

For example, as illustrated by FIG. 7G, the first color sub-pixel blocks111 in the first sub-pixel row 710 and the second color sub-pixel blocks112 and the third color sub-pixel blocks 113 in the second sub-pixel row720 which is adjacent to the first sub-pixel row 710 may be controlledby the same row of pixel circuits 250. So that, in the presentdisclosure, four sub-pixel rows 700 (including two first sub-pixel rows710 and two second sub-pixel rows 720) can be controlled by two rows ofpixel circuits.

For example, as illustrated by FIG. 7F and 4G, the first color sub-pixelblocks 111 in virtual rectangles belonging to the same column arelocated in a first sub-pixel column 810, each of the plurality ofminimum repeating regions 100 includes two first sub-pixel columns 810,and a second sub-pixel column 820 is provided between the two firstsub-pixel columns 810, the second sub-pixel column 820 includes multiplesecond color sub-pixel blocks 112 and multiple third color sub-pixelblocks 113 alternately arranged in the second direction, and multiplefirst sub-pixel columns 810 and multiple second sub-pixel columns 820are alternately arranged in the first direction. The first colorsub-pixel blocks 111 in the first sub-pixel column are controlled by thesame column of pixel circuits 250 (for example, the anodes used fordriving the first color sub-pixel blocks 111 in the first sub-pixelcolumn 810 are electrically connected the pixel circuits 250 of the samecolumn), so as to be driven by one data line 270, and the second colorsub-pixel blocks 112 and the third color sub-pixel blocks 113 in thesecond sub-pixel column 820 are also controlled by the same column ofpixel circuits 250 (for example, the anodes used for driving the secondcolor sub-pixel blocks 112 and the third color sub-pixel blocks 113 inthe second sub-pixel column 820 are electrically connected the pixelcircuits 250 of the same column), so as to be controlled by one dataline 270.

For example, as illustrated by FIG. 7F, each of the plurality of minimumrepeating regions 100 averagely includes four sub-pixel rows 700(including two first sub-pixel row 710 and two second sub-pixel row 720)and four sub-pixel columns 800 (including two first sub-pixel column 810and two second sub-pixel column 820), and the four sub-pixel rows 700and four sub-pixel columns 800 constitute two pixel rows 910 and twopixel columns 920. In this way, a ratio of the number of the sub-pixelrows to the number of the pixel rows in the second direction issubstantially the same as a ratio of the number of the sub-pixel columnsto the number of the pixel columns in the first direction.

It is to be noted that, in the first direction, the number of thesub-pixels averagely distributed each pixel is ⅔ of the number of RGBsub-pixels needed by the pixel to achieve full-color display. Besides,in the second direction, the number of the sub-pixels averagelydistributed each pixel is ⅔ of the number of RGB sub-pixels needed bythe pixel to achieve full-color display.

FIG. 8 is a pixel arrangement structure provided by an embodiment of thepresent disclosure. As illustrated by FIG. 8, first color sub-pixelblocks 111 in a third virtual rectangle 130 and a fourth virtualrectangle 140 are replaced with fourth color sub-pixel blocks 114.

For example, the first color sub-pixel block 111 includes a greensub-pixel, and the fourth color sub-pixel block 114 includes a yellowsub-pixel. Therefore, a four-color mode of red, green, blue and yellow(RGBY) may be used in the pixel arrangement structure, so as to furtherimprove display quality of the pixel arrangement structure.

FIG. 9 is a pixel arrangement structure provided by an embodiment of thepresent disclosure. As illustrated by FIG. 9, first color sub-pixelblocks 111 in a first virtual rectangle 110 and a third virtualrectangle 130 are replaced with fifth color sub-pixel blocks 115.

For example, the first color sub-pixel block 110 includes a greensub-pixel, and the fifth color sub-pixel block 115 includes a whitesub-pixel. Therefore, a red, green, blue and white (RGBW) mode may beused in the pixel arrangement structure, so as to effectively improvebrightness of the pixel arrangement structure and improve utilizationefficiency of energy.

An embodiment of the present disclosure further provides a displaysubstrate. FIG. 10 is the display substrate provided by the embodimentof the present disclosure. As illustrated by FIG. 10, the displaysubstrate includes a base substrate 101 and a plurality of pixels 200arranged on the base substrate 101. The plurality of pixels 200 mayadopt the pixel arrangement structure provided by any one of theabove-described examples. Because the display substrate may adopt thepixel arrangement structure provided by any one of the above-describedexamples, the display substrate has advantageous effects of the pixelarrangement structure included therein, for example, the displaysubstrate can improve uniformity of distribution of first colorsub-pixel blocks, so as to improve visual resolution and also improvedisplay quality.

FIG. 11 is a partial schematic plan view of another display substrateprovided by an embodiment of the present disclosure. FIG. 12 is across-sectional schematic diagram of the display substrate taken alongdirection A-A′ in FIG. 11 provided by the embodiment of the presentdisclosure. As illustrated by FIG. 11, a first color sub-pixel block 111includes a first color pixel electrode 1110 and a first colorlight-emitting layer 1111 provided on the first color pixel electrode1110, a second color sub-pixel block 112 includes a second color pixelelectrode 1120 and a second color light-emitting layer 1121 provided onthe second color pixel electrode 1120, and a third color sub-pixel block113 includes a third color pixel electrode 1130 and a third colorlight-emitting layer 1131 provided on the third color pixel electrode1130. Thus, the display substrate may be an array substrate.

For example, in some examples, the first color pixel electrode 1110 isconfigured to drive the first color light-emitting layer 1111 to emitlight.

For example, a shape of the first color pixel electrode 1110 may be thesame as a shape of the first color sub-pixel block 111. Of course, theembodiment of the present disclosure includes, but is not limitedthereto, the shape of the first color pixel electrode 1110 may bedifferent from the shape of the first color sub-pixel block 111, and theshape of the first color sub-pixel block 111 may be defined by a pixeldefining layer.

It should be noted that, the shape of the above-described first colorsub-pixel block is a shape of a light-emitting region of the first colorsub-pixel block. In addition, a specific shape of the first colorlight-emitting layer may be set according to a preparation process,which will not be limited here in the embodiment of the presentdisclosure. For example, the shape of the first color light-emittinglayer may be determined by a shape of an opening of a mask in thepreparation process.

For example, the first color pixel electrode 1110 may be in contact withthe first color light-emitting layer 1111, so that it can drive thelight-emitting layer to emit light at a portion in contact with eachother, and the portion where the first color pixel electrode 1110 andthe first color light-emitting layer 1111 can be in contact with eachother is an effective portion that a sub-pixel can emit light.Therefore, the shape of the above-described first color sub-pixel blockis the shape of the light-emitting region of the first color sub-pixelblock. In the embodiment of the present disclosure, the first colorpixel electrode 1110 may be an anode, but is not limited to an anode,and a cathode of a light emitting diode may also be used as the pixelelectrode.

For example, in some examples, the second color pixel electrode 1120 isconfigured to drive the second color light-emitting layer 1121 to emitlight.

For example, a shape of the second color pixel electrode 1120 may be thesame as a shape of the second color sub-pixel block 112. Of course, theembodiment of the present disclosure includes, but is not limitedthereto, the shape of the second color pixel electrode 1120 may bedifferent from the shape of the second color sub-pixel block 112, andthe shape of the second color sub-pixel block 112 may be defined by apixel defining layer.

It should be noted that, the shape of the above-described second colorsub-pixel block is a shape of a light-emitting region of the secondcolor sub-pixel block. In addition, a specific shape of the second colorlight-emitting layer may be set according to a preparation process,which will not be limited here in the embodiment of the presentdisclosure. For example, the shape of the second color light-emittinglayer may be determined by a shape of an opening of a mask in thepreparation process.

For example, the second color pixel electrode 1120 may be in contactwith the second color light-emitting layer 1121, so that it can drivethe light-emitting layer to emit light at a portion in contact with eachother, and the portion where the second color pixel electrode 1120 andthe second color light-emitting layer 1121 can be in contact with eachother is an effective portion that a sub-pixel can emit light.Therefore, the shape of the above-described second color sub-pixel blockis the shape of the light-emitting region of the second color sub-pixelblock. In the embodiment of the present disclosure, the second colorpixel electrode 1120 may be an anode, but is not limited to an anode,and a cathode of a light emitting diode may also be used as the pixelelectrode.

For example, in some examples, the third color pixel electrode 1130 isconfigured to drive the third color light-emitting layer 1131 to emitlight.

For example, a shape of the third color pixel electrode 1130 may be thesame as a shape of the third color sub-pixel block 113. Of course, theembodiment of the present disclosure includes, but is not limitedthereto, the shape of the third color pixel electrode 1130 may bedifferent from the shape of the third color sub-pixel block 113, and theshape of the third color sub-pixel block 113 may be defined by a pixeldefining layer.

It should be noted that, the shape of the above-described third colorsub-pixel block is a shape of a light-emitting region of the third colorsub-pixel block. In addition, a specific shape of the third colorlight-emitting layer may be set according to a preparation process,which will not be limited here in the embodiment of the presentdisclosure. For example, the shape of the third color light-emittinglayer may be determined by a shape of an opening of a mask in thepreparation process.

For example, the third color pixel electrode 1130 may be in contact withthe third color light-emitting layer 1131, so that it can drive thelight-emitting layer to emit light at a portion in contact with eachother, and the portion where the third color pixel electrode 1130 andthe third color light-emitting layer 1131 can be in contact with eachother is an effective portion that a sub-pixel can emit light.Therefore, the shape of the above-described third color sub-pixel blockis the shape of the light-emitting region of the third color sub-pixelblock. In the embodiment of the present disclosure, the third colorpixel electrode 1130 may be an anode, but is not limited to an anode,and a cathode of a light emitting diode may also be used as the pixelelectrode.

It should be noted that, with respect to each sub-pixel, an area of apixel electrode may be slightly larger than an area of a light-emittinglayer, or the area of the light-emitting layer may also be slightlylarger than the area of the pixel electrode, which will not beparticularly limited in the embodiment of the present disclosure. Forexample, the light-emitting layer here may include an electroluminescentlayer itself as well as other functional layers located on both sides ofthe electroluminescent layer, for example, a hole injection layer, ahole transport layer, an electron injection layer, an electron transportlayer, and so on. In some embodiments, a shape of a sub-pixel may alsobe defined by a pixel defining layer. For example, a lower electrode(e.g., an anode) of a light emitting diode may be provided below thepixel defining layer; the pixel defining layer includes an opening fordefining the sub-pixel; the opening exposes a portion of the lowerelectrode; and when a light-emitting layer is formed in the opening inthe above-described pixel defining layer, the light-emitting layer is incontact with the lower electrode, which can drive the light-emittinglayer to emit light at the portion. Therefore, in this case, the openingof the pixel defining layer defines the shape of the sub-pixel.

For example, the shapes of the various sub-pixels as described in theembodiment of the present disclosure are all approximate shapes; andwhen the light-emitting layer or various electrode layers are formed, itcannot be ensured that an edge of a sub-pixel is a strict straight lineand a corner thereof is a strict angle. For example, the light-emittinglayer may be formed by using an evaporation process with a mask, andthus, its corner portion may have a rounded shape. In some cases, adraft angle is needed in a metal etching process, so when alight-emitting layer of a sub-pixel is formed by using an evaporationprocess, a corner of the light-emitting layer may be removed.

For example, in some examples, as illustrated by FIG. 11 and FIG. 12,within a same minimum repeating region 100, a first color light-emittinglayer 1111 of a first color sub-pixel block 111 of a third virtualrectangle 130 and a first color light-emitting layer 1111 of a firstcolor sub-pixel block 111 of a fourth virtual rectangle 140 may beformed by sharing a same single color pattern region, for example,formed through a same opening of a mask.

For example, in some examples, an area of the first color light-emittinglayer 1111 of the first color sub-pixel block 111 of the third virtualrectangle 130 and the first color light-emitting layer 1111 of the firstcolor sub-pixel block 111 of the fourth virtual rectangle 140 formed bysharing a same single color pattern region is larger than a sum of anarea of a first color pixel electrode 1110 of the first color sub-pixelblock 111 of the third virtual rectangle 130 and an area of a firstcolor pixel electrode 1110 of the first color sub-pixel block 111 of thefourth virtual rectangle 140.

For example, in some examples, because a distance between a center ofthe first color sub-pixel block 111 of the third virtual rectangle 130and a center of the first color sub-pixel block 111 of the fourthvirtual rectangle 140 is larger than ½ of a length of a second edge1102, the area of the first color light-emitting layer 1111 of the firstcolor sub-pixel block 111 of the third virtual rectangle 130 and thefirst color light-emitting layer 1111 of the first color sub-pixel block111 of the fourth virtual rectangle 140 formed by sharing a same singlecolor pattern region is larger than 1.5 times the sum of the area of thefirst color pixel electrode 1110 of the first color sub-pixel block 111of the third virtual rectangle 130 and the area of the first color pixelelectrode 1110 of the first color sub-pixel block 111 of the fourthvirtual rectangle 140.

For example, in some examples, as illustrated by FIG. 11 and FIG. 12,within two minimum repeating regions 100 adjacent to each other in asecond direction, the adjacent two minimum repeating regions 100 in thesecond direction include a first minimum repeating region 1001 and asecond minimum repeating region 1002 sequentially arranged in the seconddirection; and a first color light-emitting layer 1111 of a first colorsub-pixel block 111 of a first virtual rectangle 110 within the firstminimum repeating region 1001 and a first color light-emitting layer1111 of a first color sub-pixel block 111 of a second virtual rectangle120 within the second minimum repeating region 1002 may be formed bysharing a same single color pattern region, for example, formed througha same opening of the mask.

For example, in some examples, an area of the first color light-emittinglayer 1111 of the first color sub-pixel block 111 of the first virtualrectangle 110 within the first minimum repeating region 1001 and thefirst color light-emitting layer 1111 of the first color sub-pixel block111 of the second virtual rectangle 120 within the second minimumrepeating region 1002 formed by sharing a same single color patternregion is larger than a sum of an area of a first color pixel electrode1110 of the first color sub-pixel block 111 of the first virtualrectangle 110 within the first minimum repeating region 1001 and an areaof a first color pixel electrode 1110 of the first color sub-pixel block111 of the second virtual rectangle 120 within the second minimumrepeating region 1002.

For example, because a distance between a center of the first colorsub-pixel block 111 of the first virtual rectangle 110 within the firstminimum repeating region 1001 and a center of the first color sub-pixelblock 111 of the second virtual rectangle 120 within the second minimumrepeating region 1002 is larger than ½ of the length of the second edge1102, the area of the first color light-emitting layer 1111 of the firstcolor sub-pixel block 111 of the first virtual rectangle 110 within thefirst minimum repeating region 1001 and the first color light-emittinglayer 1111 of the first color sub-pixel block 111 of the second virtualrectangle 120 within the second minimum repeating region 1002 formed bysharing a same single color pattern region is larger than 1.5 times thesum of the area of the first color pixel electrode 1110 of the firstcolor sub-pixel block 111 of the first virtual rectangle 110 within thefirst minimum repeating region 1001 and the area of the first colorpixel electrode 1110 of the first color sub-pixel block 111 of thesecond virtual rectangle 120 within the second minimum repeating region1002.

For example, in some examples, a first color sub-pixel block 111, asecond color sub-pixel block 112 and a third color sub-pixel block 113may separately serve as one sub-pixel for display; and a first colorsub-pixel block 111, a second color sub-pixel block 112 and a thirdcolor sub-pixel block 113 in each virtual rectangle may constitute apixel unit for color display.
